Formation and Eruption of Filament Channel in Solar Active Region 12975: Insights from Observations and Simulations of Magnetic Field Evolution

Dinesh Mishra, P. Vemareddy, Brajesh Kumar

We studied the magnetic field evolution of active region (AR) 12975 using a time-dependent magnetofrictional (TMF) model. This AR produced two consecutive CMEs associated with M-cl…

SN 2018gj: A Short-plateau Type II Supernova with Persistent Blue-shifted H-alpha Emission

Rishabh Singh Teja, Avinash Singh, D. K. Sahu +7

We present an extensive, panchromatic photometric (UV, Optical, and NIR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on the ou…

Far-Ultraviolet to Near-Infrared Observations of SN 2023ixf: A high energy explosion engulfed in complex circumstellar material

Rishabh Singh Teja, Avinash Singh, Judhajeet Basu +13

We present early-phase panchromatic photometric and spectroscopic coverage spanning far-ultraviolet (FUV) to the near-infrared (NIR) regime of the nearest hydrogen-rich core-collap…

On the propagation of gravity waves in the lower solar atmosphere in different magnetic configurations

Hirdesh Kumar, Brajesh Kumar, S. P. Rajaguru

Gravity waves are generated by turbulent subsurface convection overshooting or penetrating locally into a stably stratified medium. While propagating energy upwards, their characte…

A study of the propagation of magnetoacoustic waves in small-scale magnetic fields using solar photospheric and chromospheric Dopplergrams: HMI/SDO and MAST observations

Hirdesh Kumar, Brajesh Kumar, S. P. Rajaguru +2

In this work, we present a study of the propagation of low-frequency magneto-acoustic waves into the solar chromosphere within small-scale inclined magnetic fields over a quiet-mag…

Type Ia supernovae SN 2013bz, PSN J0910+5003 and ASASSN-16ex: similar to 09dc-like?

S. Tiwari, N. K. Chakradhari, D. K. Sahu +3

We present optical photometric and spectroscopic studies of three supernovae (SNe) SN 2013bz, PSN J0910+5003 and ASASSN-16ex. UV-optical photometric data of ASASSN-16ex obtained wi…
