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…
Critical Metallicity of Cool Supergiant Formation. II. Physical Origin
Po-Sheng Ou, Ke-Jung Chen
This study investigates the physical origin of the critical metallicity required for the formation of cool supergiants, as revealed by stellar evolution models. Using grids of stel…
Discovery and Extensive Follow-Up of SN 2024ggi, a nearby type IIP supernova in NGC 3621
Ting-Wan Chen, Sheng Yang, Shubham Srivastav +45
We present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 +/- 0.3 Mpc. The SN was caught 5.8 (+1.9 -2.9) hours after its expl…
Stellar Population near NGC 2021: Procession of Star Formation in the South Rim of Supergiant Shell LMC 4
Po-Sheng Ou, Rui-Ching Chao, You-Hua Chu +2
Supergiant shells (SGSs) are the largest interstellar structures where heated and enriched gas flows into the host galaxy's halo. The SGSs in the Large Magellanic Cloud (LMC) are s…
