On the Nature of the BeWD System Nova FQ Circinus

Shatakshi Chamoli, Philip A. Charles, Judhajeet Basu +3

The classical nova FQ Cir (Schaefer et al. 2026) has recently been shown to have a Be star donor, and has been identified as a High Mass Cataclysmic Variable (HMCV), with an orbita…

Ensemble pulsational characteristics of eclipsing binaries containing Cep stars observed by the TESS mission

C. I. Eze, G. Handler, M. Vanrespaille +4

Massive pulsators in eclipsing binaries provide precise, model-independent stellar parameters that, combined with asteroseismic constraints, provide powerful probes of interior pro…

ALMA's sharpest view of IRAS 08544-4431: Unveiling the dust distribution asymmetries in the circumbinary disk

Maksym Mohorian, Devika Kamath, Elizabeth Cappellazzo +10

The interactions between post-asymptotic giant branch (post-AGB) binaries and their circumbinary disks play a central role in shaping the evolution of these systems. Circumbinary d…

Orbital and stellar parameter determination of eclipsing Cep pulsators

C. I. Eze, G. Handler, F. Kahraman Aliçavuş +2

Eclipsing binaries provide precise constraints on stellar properties and evolution, making those hosting Cep pulsators particularly valuable for characterising massive pulsatin…

Gaia method paper: an algorithm to detect flare events in Gaia time-series

E. Distefano, A. C. Lanzafame, A. F. Lanza +14

The third Gaia data release (GDR3) includes the gdr3_rotmod catalogue of 474026 stars with variability that is attributed to magnetic activity analogous to that observed in the Sun…

Precise physical and kinematical parameters of massive eclipsing binaries in the Small Magellanic Cloud

M. Kaya, Ö. Çakırlı, B. Hoyman +3

The formation of massive stars serves an important field of study, requiring research into whether these stars need to form together within clusters of low-mass stars or if they ar…

SPIRITS 19q: Dust Production by a Subsolar-metallicity Carbon-rich Wolf-Rayet Star in NGC 2403

Sam Rose, Ryan M. Lau, Jacob E. Jencson +20

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

Tongtian Ren, Michael A. Garrett, Erik Zackrisson +4

We report on the diagnostic investigation of nine Project Hephaistos Dyson Sphere candidate M-dwarfs based on archival data. By comparing the Gaia DR3 positions with epoch 2016.0,…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

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…

A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs

Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72

We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-res…
