Discovery of an Extremely Luminous Type II Cepheid in the Andromeda Giant Stellar Stream: Evidence for a Hierarchical Triple with an Inner Binary Merger

open access: yesThe Astrophysical Journal Letters
We report the discovery of LAMOST J0041+3948, the most luminous post-asymptotic giant-branch (AGB) Type II Cepheid known, located in the Andromeda Giant Stellar Stream.

A Detailed Analysis of the Milky Way Warp Based on Classical Cepheids

open access: yesThe Astrophysical Journal
Classical Cepheids (CCs) are important probes for the large-scale warp structure of the Milky Way. Using Gaia Data Release 3 CCs, we establish an optimal time-dependent warp model, where the warp height increases with radius following a power law, the ...

The Rotational and Magnetic Properties of Polaris from Long-term Spectropolarimetric Monitoring

open access: yesThe Astrophysical Journal
Polaris is a highly unusual Cepheid with observed properties that are difficult to reconcile with stellar evolutionary models. Since the initial detection of Polaris’ magnetic field in 2020, we have conducted a magnetic monitoring campaign with the ...
