Dynamic Photometric Variability in Three Young Brown Dwarfs in Taurus: Detection of Optical Flares with TESS data
Samrat Ghosh, Soumen Mondal, Somnath Dutta +4
We present -band time-series photometric variability studies of three known nearby ( 140 pc) and young ( 1 Myr) brown dwarfs (BD) in the Taurus star-forming region…
Starspot distribution and flare events in two young low-mass stars using TESS data
Rajib Kumbhakar, Soumen Mondal, Samrat Ghosh +1
Wide-field high-precision photometric observations such as \textit{Transiting Exoplanet Survey Satellite (TESS)} allowed the investigation of the stellar magnetic activity of cool…
Photometric Variability of Low Mass Stars and Brown Dwarfs in IC~348 and Taurus Star-Forming Regions
Samrat Ghosh, Soumen Mondal, Santosh Joshi +2
Low-mass stars belonging to the M spectral type are the most numerous stars in our Galaxy, amounting to about two-thirds in number, and are found at the bottom of the main sequence…
Rotational Variability and Detection of Superflares in a Young Brown Dwarf by TESS
Rajib Kumbhakar, Soumen Mondal, Samrat Ghosh +2
We present a comprehensive analysis of a Transiting Exoplanet Survey Satellite (TESS) high-quality light curve for a young brown dwarf, MHO~4 having spectral type M7.0, in the Taur…
