A. O. Simon, A. V. Bondar, N. V. Metlova
TL;DR
This paper presents spectroscopic evidence of a new decretion disk formation around IGR J06074+2205, indicating potential upcoming X-ray activity, with measurements of disk size derived from spectral line analysis.
Contribution
It reports the first spectroscopic detection of a new decretion disk around IGR J06074+2205 and measures its radius using H-alpha line data.
Findings
Detected a new decretion disk formation episode.
Measured disk radius as approximately 1.6 times the star's radius.
Suggests possible future X-ray activity from the system.
Abstract
We report about new episode of decretion disk formation in the IGR J06074+2205 system. Obtained spectral data gives us opportunity to measure peak separation in double-peaked H\alpha\ line as 408+/-55 km/s and hence obtain disk radii as 1.6 star radii. All these facts may says about possible X-ray activity of IGR J06074+2205 in the nearest future.
