Revisiting the Transit Timing Variations in the TrES-3 and Qatar-1 systems with TESS data
Vineet Kumar Mannaday, Parijat Thakur, John Southworth +12
We present and analyze 58 transit light curves of TrES-3b and 98 transit light curves of Qatar-1b observed by Transiting Exoplanet Survey Satellite (TESS), plus two transit light c…
Can the violent merger of white dwarfs explain the slowest declining Type Ia supernova SN 2011aa?
Anirban Dutta, G C Anupama, N K Chakradhari +1
We present optical observations and Monte Carlo radiative transfer modeling of the Type Ia supernova SN 2011aa. With a of mag and a peak magnitude $M_…
MUSSES2020J: The Earliest Discovery of a Fast Blue Ultraluminous Transient at Redshift 1.063
Ji-an Jiang, Naoki Yasuda, Keiichi Maeda +22
In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by using the Hyper Suprime-…
Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
SN 2020jfo: A short plateau Type II supernova from a low mass progenitor
Rishabh Singh Teja, Avinash Singh, D. K. Sahu +3
We present spectroscopic and photometric observations of the Type IIP supernova, SN 2020jfo, in ultraviolet and optical wavelengths. SN 2020jfo occurred in the spiral galaxy M61 (N…
Investigating the observational properties of Type Ib supernova SN 2017iro
Brajesh Kumar, Avinash Singh, D. K. Sahu +1
We report results of optical imaging and low-resolution spectroscopic monitoring of supernova (SN) 2017iro that occurred in the nearby (\,31 Mpc) galaxy NGC 5480. The \ion{He…
