Aditya-L1 and SDO Observations of a Confined X-Class Flare with an EUV Late Phase: Thermal and Nonthermal Emission, Magnetic Topology, and Flux Rope Confinement

Vishwa Vijay Singh, Bhuwan Joshi, N. P. S. Mithun

We study a long-duration, confined X2.0-class solar flare exhibiting three distinct episodes of HXR emission, along with an accompanying EUV late phase. A key highlight of this wor…

Magnetic Fields in Massive Star-forming Regions (MagMaR). IX. Radiative Torque Alignment and Disruption in NGC6334I

Vineet Rawat, Thiem Hoang, Patricio Sanhueza +18

Intense radiation from high-mass stars is expected to significantly affect dust grain alignment and evolution through RAdiative Torques (RATs). We investigate this effect in a mass…

Multi-Wavelength Diagnostics of Pre-Flare Evolution with Aditya-L1: From the Solar Chromosphere to the Corona

Adithya H. N., Sreejith Padinhatteeri, Soumya Roy +13

The pre-flare phase of solar flares provides important insight into the processes that drive active regions toward instability. We investigate chromospheric pre-flare activity usin…

A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2

C. Swastik, M. Bestha, L. S. Sonith +11

WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…

Can We Find the Emission Mechanism Behind the Extremely Bright GRB 230812B?

Utkarsh Pathak, Sameer K. Patil, Hitesh Tanenia +23

GRB 230812B is a bright long-duration GRB with a luminous, long-lived afterglow and an AstroSat/CZTI polarization measurement during the prompt phase, enabling a joint study of its…

Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system

Federica Rescigno, Manu Stalport, Ancy Anna John +28

We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…
