Observable Signatures of Supernova Shock Breakout in Confined Circumstellar Medium

Wun-Yi Chen, Ke-Jung Chen, Keiichi Maeda +1

Supernova shock breakout encodes rich information about stellar explosions, including the properties of the progenitor, the explosion mechanism, and the circumstellar environment.…

Interacting Binary Stars as Progenitors for Interacting Supernovae

Sung-Han Tsai, Ke-Jung Chen, Keiichi Maeda +2

Dense, compact circumstellar media (CSM) are required to power strongly interacting supernovae, yet their physical origin remains uncertain. We present a systematic study of binary…

Accurate Determination of Chemical Abundances near a Supermassive Black Hole

The XRISM collaboration

The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…

Multi-wavelength Signatures of Supernova Shock Breakout from Red Supergiants in Two Dimensions

Wun-Yi Chen, Ke-Jung Chen, Keiichi Maeda +3

We present new two-dimensional radiation hydrodynamic simulations of supernova shock breakout from red supergiants using the code. Our progenitors are 20 and 25 M…

Fading Echoes of Interaction: Probing Centuries of Preexplosion Mass-Loss in Four Type IIn Supernovae

Elizabeth Hillenkamp, Raphael Baer-Way, Poonam Chandra +6

Supernovae characterized by enduring narrow optical hydrogen emission lines (SNe IIn) are believed to result primarily from the core-collapse of massive stars undergoing sustained…
