The Evolutionary Status of SS 433.
We consider possible evolutionary models for SS 433. We assume that common envelope evolution is avoided if radiation pressure is able to expel most of a super-Eddington accretion flow from a region smaller than the accretor's Roche lobe. This condition is satisfied, at least initially, for largely radiative donors with masses in the range 4-12 M middle dot in circle. For donors more massive th...
متن کاملX-ray Observation of SS 433 with RXTE
Apart from regular monitoring by ASM, the compact object SS 433 was observed with RXTE several times last two/three years. We present the first analysis of these observations. We also include the results of the recent exciting TOO campaign made during donour inferior (orbital phase φ = 0) and superior (φ = 0.5) conjunctions which took place on Oct. 2nd, 2003, and on March 13th, 2004 respectivel...
متن کاملOF AN EQUATORIAL OUTFLOW IN SS 433 Katherine
We have imaged the X-ray binary SS 433 with unprecedented Fourier plane coverage at 6 cm using simultaneously the Very Long Baseline Array (VLBA), MERLIN, and the Very Large Array and also at 20 cm using the VLBA. At both wavelengths we have securely detected smooth, low surface brightness emission having the appearance of a “ruff” or collar attached perpendicularly to the well-studied knotty j...
متن کاملSS-433/W50 at TeV Energies
The HEGRA CT-System was used to search for TeV gammarays from the microquasar and supernova remnant combination SS433/W50 over the 1998 and 1999 observing seasons, resulting in about 20 hours of useful data. An analysis of various extended sources of location guided by X-Ray observations reveals no evidence for TeV emission at photon energies above 1 TeV, with resulting 99% upper limits in the ...
متن کاملNew VLBI observations of SS 433
The unique object SS433 is brieey reviewed with particular reference to the part played by the stellar wind ejected by the early type companion star. The aims of this observational campaign are described and the theory of the mass loss rate measurements explained. VLBA 1.6 GHz maps are presented as well as preliminary 23 GHz VLA and MERLIN maps. Mass loss rates of around 510 ?6 M yr ?1 are foun...
