Gaia DR3 Open Cluster Cepheids: A Unified Catalog with Calibrated Period–Age and Period–Wesenheit Relations

open access: yesThe Astronomical Journal
Classical Cepheids (CCs) in Galactic open clusters (OCs) provide essential observational constraints for calibrating the period–age relation (PAR) and the period–Wesenheit relation (PWR) of CCs. However, distant and long-period OC Cepheids remain limited,

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.

Is Crater II Disrupting?

open access: yesThe Astronomical Journal
Crater II (CraII) is a very intriguing low surface brightness and extended galaxy in the vicinity of our Galaxy. Motivated by its huge area and the number of RR Lyrae stars (RRLSs) detected near to its core, we performed a follow-up campaign to get deep ...

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 ...
