S0-2 star, G1- and G2-objects, and flaring activity of the Milky Way's Galactic Center black hole in 2019.

MURCHIKOVA L.

Abstract (from CDS):

In 2019, the Galactic center black hole Sgr A* produced an unusually high number of bright near-infrared flares, including the brightest-ever detected flare. We propose that this activity was triggered by the near simultaneous infall of material shed by G1 and G2 objects due to their interaction with the background accretion flow. We discuss mechanisms by which S-stars and G-objects shed material, and estimate both the quantity of material and the infall time to reach the black hole.
