Catalogue of unresolved white dwarf-main sequence binaries from Gaia DR3
Astronomers compiled a large catalog of binary star systems containing a white dwarf and a main-sequence star using data from Gaia DR3. This catalog helps study the evolution of such binaries and includes detailed stellar parameters and eclipsing systems.
Why it matters: The catalog expands the sample of known WDMS binaries, crucial for understanding binary star evolution.
The big picture: The study improves modeling of binary populations by comparing observed data with synthetic Galactic samples.
Stunning stat: The catalog contains 1312 WDMS binaries, with stellar parameters derived for 435 and 67 identified eclipsing systems.
The stakes: Sample incompleteness and observational biases limit full understanding but still provide a valuable, well-characterized dataset.
