Radial Velocity Studies of Close Binary Stars
نویسنده
چکیده
Radial-velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for ten close binary systems: OO Aql, CC Com, V345 Gem, XY Leo, AM Leo, V1010 Oph, V2612 Oph, XX Sex, W UMa, and XY UMa. Most of these binaries have been observed spectroscopically before, but our data are of higher quality and consistency than in the previous studies. While most of the studied eclipsing pairs are contact binaries, V1010 Oph is probably a detached or semi-detached double-lined binary and XY UMa is a detached, chromospherically active system whose broadening functions clearly show well defined and localized dark spots on the primary component. A particularly interesting case is XY Leo, which is a member of visually unresolved quadruple

Radial Velocity Studies of Southern Close Binary Stars . II . Spring / Summer Systems 1
Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for 14 close binary stars, S Ant, TT Cet, TW Cet, AA Cet, RW Dor, UX Eri, YY Eri, BV Eri, CT Eri, SZ Hor, AD Phe, TY Pup, HI Pup and TZ Pyx. All are double-lined binaries and all except the last one are contact binaries. The orbital data must be considered preliminary because of the relatively smal...
متن کاملVelocity curve analysis of spectroscopic binary stars EQ Tau, V376 And, V776 Cas, V2377 Oph and V380 Cygni by nonlinear regression
Using measured radial velocity data of five double-lined spectroscopic binary systems EQ Tau, V376 And, V776 Cas, V2377 Oph and V380 Cygni, we find corresponding orbital and spectroscopic elements via the method introduced by Karami & Teimoorinia and Karami & Mohebi. Our numerical results are in good agreement with those obtained by others using more traditional methods.

متن کاملThe Incidence of Stellar Mergers and Mass Gainers among Massive Stars
Because the majority of massive stars are born as members of close binary systems, populations of massive main-sequence stars contain stellar mergers and products of binary mass transfer. We simulate populations of massive stars accounting for all major binary evolution effects based on the most recent binary parameter statistics and extensively evaluate the effect of model uncertainties. Assum...
