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 $\text{CASTRO}$ code. Our progenitors are 20 and 25 M…
