A Spectroscopic study of the non - thermal radio emitter Cyg OB 2 # 8 A : Discovery of a new binary system ⋆
We present the results of a spectroscopic campaign revealing that the non-thermal radio emitter Cyg OB2 #8A is an O6 + O5.5 binary system. We propose the very first orbital solution indicating a period of about 21.9 days. The system appears to be eccentric (0.24 ± 0.04) and is likely seen under a rather low inclination angle. The mass ratio of the components is close to unity. The impact of the...
متن کاملThe Orbital Period of HDE 226868 / Cyg X - 1 3
We present epoch 1996, high-quality radial velocity data for HDE 226868, the optical counterpart of Cygnus X-1. Combining our results with all published historical data, we have derived a new ephemeris for the system of HJD2450235.29 +n×5.5998, which allows accurate orbital phase calculations to be made for any X-ray observations over the last 30 years. We find no evidence for any period change...
متن کاملIPHAS discoveries of young stars towards Cyg OB2 and its southern periphery
We report on the discovery of over 50 strong Hα emitting objects towards the large OB association Cyg OB2 and the Hii region DR 15 on its southern periphery. This was achieved using the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS), combined with follow-up spectroscopy using the MMT multi-object spectrometer HectoSpec. We present optical spectra, supplemented with optical r, ...
متن کاملFundamental parameters of Galactic luminous OB stars VI. Temperatures, masses and WLR of Cyg OB2 supergiants
We have analyzed six OB supergiants and one giant covering spectral types from O3 to B1 in the Galactic OB association Cyg OB2 by means of an updated version of FASTWIND (Santolaya–Rey et al., 1997) that includes an approximate treatment of metal line blocking and blanketing. This large coverage in spectral type allows us to derive a new temperature scale for Galactic O supergiants that is lowe...
متن کاملXMM - Newton observations of the massive colliding wind binary and non - thermal radio emitter Cyg OB 2 # 8 A ( O 6 If + O 5 . 5 III ( f ) ) ?
We report on the results of four XMM-Newton observations separated by about ten days from each other of Cyg OB2 #8A (O6If + O5.5III(f)). This massive colliding wind binary is a very bright X-ray emitter – one of the first X-ray emitting O-stars discovered by the Einstein satellite –as well as a confirmed non-thermal radio emitter whose binarity was discovered quite recently. The X-ray spectrum ...
