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…
SGR 1935+2154's Quiet Local Environment: Clues for Its Progenitor
Wenlang He, Ping Zhou, Bingqiu Chen
Magnetars are highly magnetized neutron stars (NSs) whose evolution and radiation are governed by the decay and/or reconfiguration of their magnetic fields. The origin of magnetars…
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…
Evolved Massive Stars at Low-metallicity VII. the Lower Mass Limit of Red Supergiant Population in the Large Magellanic Cloud
Ming Yang, Bo Zhang, Biwei Jiang +8
The precise definition of the lower mass limit of red supergiant stars (RSGs) is an open question in astrophysics and does not attract too much attention. Here we assemble a spectr…
A three dimensional extinction map of the Galactic Anticentre from multi-band photometry
B. -Q Chen, X. -W. Liu, H. -B. Yuan +8
We present a three dimensional extinction map in band. The map has a spatial angular resolution, depending on latitude, between 3 -- 9\,arcmin and covers the entire XSTPS-GAC s…
