A Uniform Census of Variable Stars in M101 Based on HST/ACS Photometry
Jiyu Wang, Xiaodian Chen, Pinjian Chen +3
We present a homogeneous HST/ACS F555W/F814W time-series census of variable stars in two M101 disk fields, using a uniform multi-band reduction and reproducible variable-selection…
GSED: The Galactic Stellar Extinction Database
Baisong Zhang, Bingqiu Chen, Dongwei Fan +9
Reliable extinction correction is essential for nearly all astrophysical studies within the Galaxy. We present the Galactic Stellar Extinction Database (GSED, https://nadc.china-vo…
A Planetary Nebula from a 5.7 Progenitor in a 90 Myr M31 Star Cluster
Pinjian Chen, Bingqiu Chen, Xiaodian Chen +2
Planetary nebulae (PNe) trace the late evolution of low-to-intermediate-mass stars, yet the masses of their progenitors are rarely measured directly. Here we present a PN physicall…
Confirmation and Refutation of Lyman Continuum Leakers at with JWST NIRSpec/IFU
Shengzhe Wang, Xin Wang, Hang Zhou +10
Our understanding of the physical mechanisms and environments conducive to the escape of Lyman-continuum (LyC) radiation within the first 2 Gyr of cosmic history remains limited. H…
Discovery of an Extremely Luminous Type II Cepheid in the Andromeda Giant Stellar Stream: Evidence for a Hierarchical Triple with an Inner Binary Merger
Pinjian Chen, Bingqiu Chen, Xiaodian Chen +7
We report the discovery of LAMOST J0041+3948, the most luminous post-AGB Type II Cepheid (TIIC) known, located in the Andromeda Giant Stellar Stream. Its spectral energy distributi…
