Deep X-ray, radio, and infrared non-detections of GRS 1915+105 imply an intrinsic decline in accretion activity rather than enhanced obscuration, likely driven by 2023-2024 outflows clearing the inner disc.

abstract
We report on the results of medium-resolution spectroscopy of GRS 1915+105 in the near-infrared H and K band using the 8m VLT at ESO. We clearly identify absorption bandheads from 12CO and 13CO. Together with other features this results in a classification of the mass-donating star in this binary as a K-M III star, clearly indicating that GRS 1915+105 belongs to the class of low-mass X-ray binaries (LMXB).

An intrinsic decline of accretion activity in GRS 1915+105
Deep X-ray, radio, and infrared non-detections of GRS 1915+105 imply an intrinsic decline in accretion activity rather than enhanced obscuration, likely driven by 2023-2024 outflows clearing the inner disc.
