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…

X-Ray Luminosity and Size Relationship of Supernova Remnants in the LMC
Po-Sheng Ou, You-Hua Chu, Pierre Maggi +3
The Large Magellanic Cloud (LMC) has 60 confirmed supernova remnants (SNRs). Because of the known distance, 50 kpc, the SNRs' angular sizes can be converted to linear sizes,…
