ASAS-SN eclipsing contact binaries with Gaia DR3
Listed in IVOA Registry (Virtual Observatory)
Description
Starting from more than 11200 short-period (less than 0.5 days) EW-type eclipsing binary candidates with the All-Sky Automated Survey for Supernovae V-band light curves, we use the Markov Chain Monte Carlo algorithm and neural networks to obtain the mass ratio (q), orbital inclination (incl), fill-out factor (f), and temperature ratio (Ts/Tp). After crossmatching with the Gaia DR3 database, the final sample contains parameters of 2399 A-type and 8712 W-type contact binaries (CBs).
We present the distributions of parameters of these 11111 short-period CBs. The mass ratio (q) and fill-out factor (f) are found to obey log-normal distributions, and the remaining parameters obey normal distributions. There is a significant period-temperature correlation of these CBs.

Additionally, the temperature ratio (Ts/Tp) tends to increase as the orbital period decreases for W-type CBs. There is no significant correlation between them for A-type CBs. The mass ratio and fill-out factor (q-f) diagram suggest there is no significant correlation between these two parameters.
A clear correlation exists between the mass ratio and radius ratio. The radius ratio increases with the mass ratio. Moreover, the deep fill-out CBs tend to fall on the upper boundary of the q-Rs/Rp distribution, while the shallow fill-out CBs fall on the lower boundary.
