Infrared spectroscopy of V 616 Mon ( = A 0620 – 00 ) : the accretion disc contamination
نویسندگان
چکیده
We have obtained for the first time K-band infrared spectra of the soft X-ray transient V616 Mon (=A0620–00). We determine the 2-σ upper limit to the fraction of light arising from the accretion disc to be 27 percent. The effect this has on the binary inclination, determined from modelling the infrared ellipsoidal variations is to increase it by less than 7 degrees and decrease the mass of the black hole by less than 3.6 M ⊙ .

متن کاملThe Nature of the Secondary Star in the Black Hole X-Ray Transient V616 Mon (=A0620-00)
We have used NIRSPEC on Keck II to obtain K-band spectroscopy of the low mass X-ray binary V616 Mon (= A0620−00). V616 Mon is the proto-typical soft x-ray transient containing a black hole primary. As such it is important to constrain the masses of the binary components. The modeling of the infrared observations of ellipsoidal variations in this system lead to a derived mass of 11.0 M⊙ for the ...

For the first time we have performed a detailed study of the X-ray, optical and infrared light curves and an intercomparison between these wavelengths (including radio) of the 1975/1976 outburst of the famous black-hole transient A0620−00 (Nova Mon 1975, V616Mon). We also investigated the optical behaviour up to a year after the main outburst. This study enabled us to find some new features, wh...
متن کاملInfrared Spectroscopy of V404 Cygni. Limits on the Accretion Disc Contamination
We have obtained for the rst time 2.10{2.45 micron infrared spectra of the soft X-ray transient V404 Cygni. We determine a 95 percent conndence upper limit to the fraction of light arising from the accretion disc of 14 percent. The eeect this has on the mass of the compact object, determined from modelling the infrared ellipsoidal variations, is to reduce its mass to at most 10 M .
