Abstract:
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.
