• Estimation of the energy involved in a solar coronal mass ejection using spectroscopic observations in the 5303Å emission line 

  Ramesh, R; Priyal, M; Singh, J; Sasikumar Raja, K; Mishra, Wageesh; Monstein, C (American Astronomical Society, 2026-07-01)

  While the amount of solar coronal energy flux leaving the "quiet" Sun, coronal holes, and active regions has been estimated by many, similar calculations for transients like coronal mass ejections (CMEs) based on observations ...
• On the relationship between solar spicules and propagating coronal disturbances: The role of shocks 

  Chaurasiya, Ravi; Srivastava, Sankalp; Chatterjee, Piyali; Dey, Sahel; Erdelyi, Robertus; Bayanna, A. R (American Astronomical Society, 2026-07-01)

  Spicules and propagating coronal disturbances (PCDs) are ubiquitous dynamic features of the solar atmosphere, yet their physical connection remains an open question of paramount importance to the mass and energy transport ...
• Subluminous type IIP SN 2024abfl as a result of a significantly low-energy Fe-core collapse 

  Teja, Rishabh Singh; Sahu, D. K; Anupama, G. C; Singh, A; Dutta, Amrit; Rameshan, Gitika; Das, Hrishav; Kawabata, K. S; Singh, Mridweeka; Bhalerao, Varun (American Astronomical Society, 2026-07-01)

  We present extensive, well-sampled multiwavelength photometric and low-resolution optical spectroscopic observations of the low-luminosity Type IIP supernova (SN) SN 2024abfl. SN 2024abfl is found to be at the faintest end ...

  We present high-resolution magnetic field maps of the M17 SW molecular cloud using JCMT 850 μm dust polarization at scale of 14″. The magnetic field exhibits a distinct arc-like structure that encircles three dense clumps ...
• JWST spectroscopy of SNe Ia 2022aaiq and 2024gy: Evidence for enhanced central stable Ni abundance and a deflagration-to-detonation transition
