Our ultimate goal is to enhance our understanding of planet formation by identifying the youngest exoplanets orbiting T Tauri Stars (TTSs), systems typically aged around or below 5 Myr. Detecting planets around TTSs poses significant challenges because of the strong stellar activity and interference from protoplanetary disks. Stellar spots, prominent on young stars, generate strong radial...

The presence of old open clusters but remaining rich in members challenges the conventional view that such systems dissociate within 1 Gyr in the typically inhospitable Galactic disk. We present a study of eight such clusters—Collinder 261, NGC 2158, NGC 2477, NGC 2506, NGC 6791, NGC 6819, NGC 7786, and Trumpler 5—each with an age comparable to those of globular clusters yet harbors thousands...

Brown dwarfs are failed stars with very low mass (13 to 75 Jupiter mass), and an effective temperature lower than 2500 K. Their mass range is between Jupiter and red dwarfs. Thus, they play a key role in understanding the gap in the mass function between stars and planets. However, due to their faint nature, previous searches are inevitably limited to the solar neighbourhood (20 pc). To...

The 2002es-like and 2003fg-like supernovae (SNe) are weirdos of SNe Ia. While their progenitor systems and explosion mechanisms are still mysterious, they were believed to have different origins from past observations. However, recent studies on their UV light curves indicated that they are actually very similar in the UV and could share the same origin. This work aims to investigate these...
