White Dwarfs in the Era of the LSST and its Synergies with Space-Based Missions

Understand

With the imminent start of the Legacy Survey for Space and Time (LSST) on the Vera C.

• Rubin Observatory, and several new space telescopes expected to begin operations later in this decade, both time domain and wide-field astronomy are on the threshold of a new era.
• In this paper, we use a new, multi-component model for the distribution of white dwarfs (WDs) in our Galaxy to simulate the WD populations in four upcoming wide-field surveys (i.e., LSST, Euclid, the Roman Space Telescope and CASTOR) and use the resulting samples to explore some representative WD science cases.
• Our results confirm that LSST will provide a wealth of information for Galactic WDs, detecting more than 150 million WDs at the final depth of its stacked, 10-year survey.
