Identifying hot subdwarf binaries with multimodal deep learning

open access: yesAstronomy & Astrophysics
Context. Hot subdwarf stars are important tracers of stellar structure and evolution, while their binary systems provide key constraints on their formation channels. Nevertheless, the number of confirmed hot subdwarf binaries is still limited. Aims.

Inferring Binary and Trinary Stellar Populations in Photometric and Astrometric Surveys

open access: yes, 2018
Multiple stellar systems are ubiquitous in the Milky Way but are often unresolved and seen as single objects in spectroscopic, photometric, and astrometric surveys.

Exoplanets in the Antarctic Sky. V. The Second Data Release of AST3-II/CHESPA and Newly Found Variables within the Southern Continuous Viewing Zone of TESS

open access: yesThe Astrophysical Journal Supplement Series
Located at Dome A, the highest point on the Antarctic plateau, China’s Kunlun station is a premier ground-based photometric observatory. Its cold, dry, and stable atmosphere allows continuous observation for over 40 days during polar winter, ideal for ...

Detecting and Characterizing Companions with a Calibrated Gaia DR2, DR3, and Hipparcos Catalog (G23H)

open access: yesThe Astronomical Journal
Gaia Data Release 4 epoch astrometry will enable the detection of thousands of exoplanets through astrometric motion. We present a composite catalog and modeling framework that extracts the maximum information from existing Hipparcos and Gaia data ...

Double Hot Jupiter Formation through Mirrored ZLK Migration in Binary Star Systems: The Case of WASP-94

open access: yesThe Astrophysical Journal Letters
To date, only a handful of binary star systems are known with at least one confirmed planet orbiting each star. Such systems, however, offer a unique perspective on the stochasticity intrinsic to planet formation and evolution—particularly in twin binary
