cds-question@unistra.frmultiple-starsvisible-astronomyspectroscopyradial-velocityClose binary interactions may play a critical role in the formation of the rapidly rotating Be-stars. Mass transfer can result in a mass gainer star spun up by the accretion of mass and angular momentum, while the mass donor is stripped of its envelope to form a hot and faint helium star. Far-UV spectroscopy has led to the detection of about 20 such binary Be+sdO systems. Here we report on a 3yr program of high-quality spectroscopy designed to determine the orbital periods and physical properties of five Be-binary systems. These binaries are long orbital period systems with P=95-237days and small semiamplitude K1<11km/s. We combined the Be star velocities with prior sdO measurements to obtain mass ratios. A Doppler tomography algorithm shows the presence of the HeII{lambda}4686-line in the faint spectrum of the hot companion in four of the targets. We discuss the observed line variability and show evidence of phase-locked variations in the emission profiles of HD157832, suggesting a possible disk spiral density wave due to the presence of the companion star. The stripped companions in HD113120 and HD137387 may have a mass larger than 1.4M{sun}, indicating that they could be progenitors of Type Ib and Ic supernovae.2023AJ....165..203Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/165/203CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/385/488 : Search for duplicity in periodic Be stars (Carrier+, 2002)J/A+A/387/580 : UBV photometry of V832 Cyg (Harmanec+, 2002)J/MNRAS/371/252 : Southern B and Be stars (Levenhagen+, 2006)J/ApJ/686/1280 : Discovery of hot subdwarf companion to FYCMa (Peters+, 2008)J/AN/331/349 : O, Btype & red supergiant masses & luminosity (Hohle+, 2010)J/MNRAS/410/190 : Young runaway stars within 3kpc (Tetzlaff+, 2011)J/A+A/545/A121 : {omicron} Puppis spectra (Koubsky+, 2012)J/A+A/537/A59 : Radial velocities of gamma Cas (Nemravov+, 2012)J/ApJ/765/2 : FUV radial velocities of 59 Cyg (Peters+, 2013)J/A+A/567/A57 : HD 161306 H{alpha} and HeI spectra (Koubsky+, 2014)J/ApJ/828/47 : Radial velocities of the Be star HR 2142 (Peters+, 2016)J/A+A/595/A132 : Be star rotational velocities distribution (Zorec+, 2016)J/MNRAS/474/5287 : BeSOS Be stars stellar parameters (Arcos+, 2018)J/A+A/629/A134 : Radiative contribution from stripped stars (Goetberg+, 2019)J/ApJ/899/132 : Adiabatic Mass Loss in Binary Stars.
