Women in Astronomy in Belgium

<p>We are attempting to gather all information available to study the question of the representation of women in astronomy in Belgium, which is not a straightforward task.</p> <p>In an early study, [1] analysed gender-specific statistics on the Belgian physicists. One of the difficulties they found was that Belgium keeps different statistics for the French-speaking and Flemish universities, and the career structure is different depending on the Communities.</p> <p>As preliminary analysis, we investigated the percentage of women in the International Astronomical Union (IAU) registered in the database for Belgium [2]. The IAU is an international organization with participation from 68 countries that covers the main areas of astronomy, including planetary science. In 2021, 32 out of 144 Belgian members were female (22%). It is important to notice that not all astronomers in Belgium, and in particular not the younger generation where the percentage of female researchers is higher, are member of IAU. Therefore we expect these values to underestimate the true number of women in the field. In view of the fact that it is the same at the level of the funding bodies and, by construction, at the universities, Earth and Space Sciences will be considered together. We will present preliminary results of our study.</p> <p><strong>References:</strong></p> <p>[1] Petra Rudolf, Vice‐President, Christine Iserentant, Muriel Vander Donckt, Nathalie Balcaen, Peggy Fredrickx, Karen Janssens, and Griet Janssen, "Women in Physics in Belgium: Still a Long Way From Achieving Gender Equality", AIP Conference Proceedings 628, 131-132 (2002) https://doi.org/10.1063/1.1505297</p> <p>[2] https://www.iau.org/administration/membership/individual/distribution/</p>

Meridian section projections: a new class of the triaxial ellipsoid projections

Historically the conformal projections have been used for mapping not only the Earth, but other celestial bodies as well. Their application enables preserving the shape of the relief features on the maps, which is extremely important for various analyses of celestial bodies’ surfaces. For many small bodies of the Solar system the International Astronomical Union recommends to apply a triaxial ellipsoid as a reference surface. But if the conformal projections for the reference surfaces of a sphere and an ellipsoid of revolution already exist, obtaining these projections for a triaxial ellipsoid will be significantly complicated, and the task of preserving the shape of relief features still actual. In general, the article deals with cylindrical and azimuthal projections of the meridian section for global mapping the celestial body surface in accordance with the idea formulated by prof. L. M. Bugaevsky. The projections are implemented for mapping of Phobos, moon of Mars.

COORDINATION OF PLANETARY COORDINATE SYSTEM RECOMMENDATIONS BY THE IAU WORKING GROUP ON CARTOGRAPHIC COORDINATES AND ROTATIONAL ELEMENTS – 2020 STATUS AND FUTURE

Our goal is to request input from the lunar and planetary community regarding issues of planetary coordinate systems and cartography standards. We begin with an overview of the work of the International Astronomical Union Working Group on Cartographic Coordinates and Rotational Elements. We briefly describe the operations and membership of the Working Group, some of the various uses of the recommendations it makes, our most recent (2018) published report and the recommendations therein, and the outlook for our next such report. We then consider several issues and questions regarding the future of the Working Group and regarding planetary cartography and planetary data spatial infrastructure in general. This includes possible near-term projects, how we and others might collect and consider community input and includes some ideas regarding possible outcomes or future work that will need to be addressed by the Working Group or other organizations.

Vesta and Ceres

Asteroids 1 Ceres and 4 Vesta are the two most massive asteroids in the asteroid belt, with mean diameters of 946 km and 525 km, respectively. Ceres was reclassified as a dwarf planet by the International Astronomical Union as a result of its new dwarf planet definition which is a body that (a) orbits the sun, (b) has enough mass to assume a nearly round shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a moon. Scientists’ understanding of these two bodies has been revolutionized in the past decade by the success of the Dawn mission that visited both bodies. Vesta is an example of a small body that has been heated substantially and differentiated into a metallic core, silicate mantle, and basaltic crust. Ceres is a volatile-rich rocky body that experienced less heating than Vesta and has differentiated into rock and ice. These two contrasting bodies have been instrumental in learning how inner solar system material formed and evolved.

Távoli csillagok és bolygóik új elnevezései

The International Astronomical Union (IAU) celebrated its 100th anniversary in 2019. To celebrate the occasion, the organisation announced a campaign for countries to name exoplanets, that is planets outside of our solar system and their stars. A total of 113 countries and autonomous regions took part in the campaign, choosing names by way of public votes. The IAU announced the 225 names chosen at a press conference on 17 December 2019 and accepted these as official (alongside the scientific names already in use). Following a brief description of exoplanets, the study categorises the planet names according to onomastic aspects and offers an overview of the names submitted to the Hungarian committee.

Australia and the International Astronomical Union: the 1973 Sydney general assembly

Formed in 1919, the International Astronomical Union is the international body representing professional astronomers. Australia joined the union soon after its formation but, due to financial difficulties, dropped out for a few years until re-joining just before World War 2. The main non-financial contribution any country can make to the union is to host one of its general assemblies that are held in different countries and cities every three years. After Australia’s bid to host a general assembly in 1967 or 1970 was unsuccessful, another bid was made for 1973. This second bid was accepted by the union’s executive council and confirmed in a letter from the union’s general secretary. The five years of planning and organisation for the assembly were made difficult by several external threats. The main one was the late proposal from Poland to move the 1973 assembly to Warsaw to celebrate the 500th anniversary of the birth of Copernicus. A compromise of an extraordinary general assembly in Poland following the ordinary one in Australia led to reduced numbers of overseas participants in Sydney. Despite this and other problems, the 1973 general assembly was regarded as highly successful.

The IAU Office of Astronomy for Education

Since January 2020, the International Astronomical Union has an Office of Astronomy for Education (OAE). The OAE, which joins the previously existing IAU Offices for Astronomy for Development (OAD), Astronomy Outreach (OAO) and Young Astronomers (OYA) is hosted at Haus der Astronomie, a center for astronomy education and outreach operated by the Max Planck Society in Heidelberg, Germany. This contribution outlines the mission of the OAE, the current state of the office, its background, mission and collaborative structure, as well as the activities that have already started or are planned for the future.

Science strategy of the African Astronomical Society (AfAS): An outcome of the Science Business held in synergy with the IAUS 356

Presented here, is a summary of discussions at African Astronomical Society (AfAS) Science Business Meeting, Addis Ababa, Ethiopia, 10-11 October 2019. This summary was deliberated with delegates of the International Astronomical Union (IAU) Symposium 356, during a lunch session of the meeting.
