We present JWST/NIRSpec IFU observations of SPIRITS 19q, the highly dust-producing carbon-rich (WC) binary candidate located in a subsolar-metallicity region of the nearby spiral g…
EncoTESS: Age-Sensitive Encodings from Raw TESS Light Curves
Phil R. Van-Lane, Joshua S. Speagle, Ryan Cloutier +3
Main sequence stars of spectral types late F through M exhibit systematic variability in photometric light curves, particularly when they are young. Rotational modulation of starsp…
Improving the Physical Interpretability of Gaussian Processes in Stellar Activity Modeling: A Study Case on Photometric Variability Among Stellar Clusters
Leslie Moranta, Jonathan Gagné, Jacqueline K. Faherty +12
Gaussian Processes (GPs) are widely used to model stellar variability in photometric surveys, but a statistically successful fit does not guarantee that the inferred hyperparameter…
Unveiling the period-bounce population of cataclysmic variables: Spectroscopic and time-domain follow-up of eROSITA-selected candidates
S. Hernández-Díaz, B. Stelzer, A. Schwope +9
During their secular evolution, cataclysmic variable stars (CVs) evolve toward shorter orbital periods () until reaching a minimum near min, after…
Asteroseismic Analysis of the Merger Product Red Giant in the Persei System
Rozália Z. Ádám, László Molnár, Róbert Szabó +7
Context. Persei is a long-period eclipsing binary system ( years) containing a red giant primary, and it is well known for its multi-faceted classification as a…
Archival Diagnostics for Potential Background Contaminantsof Project Hephaistos Dyson Sphere Candidates

We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
The Variability of Radio Stars
Laura N. Driessen, Alex Andersson, Joseph R. Callingham +6
Stellar radio emission is highly variable with stellar flares lasting from milliseconds to hours. For some stars, their flares or bursts can repeat once every couple of hours, whil…
