I will present and overview of the Gaia mission and its most recent data release. The presentation will focus on the Gaia mission status and the plans for the extended mission, as well as the astrometric and photometric data in relation to stellar physics research.
As part of Gaia DR3, an extensive astrophysical characterisation of Galactic and extra-galactic sources has been published. In my presentation, I will provide an overview of the various different types of stellar-parameter estimates included in Gaia DR3. Some of these apply to specific types of stars while other parameterisations are general. These stellar-parameter estimates also make use of...
The Gaia Data Release 3 (DR3, published in June 2022) has delivered astrometric, photometric, and spectroscopic measurements for more than a billion stars. The wealth and complexity of the data makes traditional approaches for estimating stellar parameters for the full Gaia dataset prohibitive. We have explored different supervised learning methods for extracting basic stellar parameters as...
