Аннотация:GRO J0422+32
A. Iyudin and F. Haberl, Max-Planck-Institut fur
Extraterrestrische Physik, report: "The x-ray nova known as GRO
J0422+32 (IAUC 5580, 5582) was detected again by the All-Sky
Monitor (ASM) on RXTE during the time period 1996 Nov. 18-1997 Jan.
15. The source flux was 4.4 mCrab in the energy band 2-10 keV,
assuming a Crab-like power-law spectrum. The data were analyzed
from the publicly available ASM quick-look results provided by the
ASM/RXTE team (http://heasarc.gsfc.nasa.gov/docs/xte/ASM). The
repeated outburst of GRO J0422+32 happened at a time consistent
with the expected outburst period of about 120 days, suspected on
the basis of earlier x-ray (BATSE, ASCA; cf. IAUC 5851) and
optical measurements (Chevalier and Ilovaisky 1995, A.Ap. 297,
103). The repetition of the nova outburst indicates similarities
between GRO J0422+32 and low-mass binary systems such as Aql X-1."
