TL;DR: In this article, the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst, were analyzed using a multiband optical light curve, covering the time from the onset of the gamma-ray event to several months after, when only detect the host galaxy.

Quest for the upcoming periastron passage of an episodic dust maker and particle accelerating colliding wind binary: WR 125
Bharti Arora,Jeewan C. Pandey,M. De Becker,Shashi B. Pandey,N. K. Chakradhari,Saurabh Sharma,Brijesh Kumar +6 more
TL;DR: In this paper, the authors carried out a long term infrared and X-ray investigation of the colliding wind binary WR 125 (WC7+O9III), which was monitored using AstroSat-Soft Xray Telescope and TIRCAM2 mounted at the back of 3.6 m Devasthal Optical Telescope.
