A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
Physical properties of trans-Neptunian object (143707) 2003 UY117 derived from stellar occultation and photometric observations
M. Kretlow, J. L. Ortiz, J. Desmars +49
Trans-Neptunian objects (TNOs) are considered to be among the most primitive objects in our Solar System. Knowledge of their primary physical properties is essential for understand…
The core collapse of a 16.5 M star
Amar Aryan, Shashi Bhushan Pandey, Rahul Gupta +2
We investigate the 1D stellar evolution of a 16.5 M zero-age main-sequence star having different initial rotations. Starting from the pre-main-sequence, the models evolve…
Prompt and afterglow analysis of the Fermi-LAT detected GRB 230812B
