An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter
Yao Wang, Yichen Zhang, Rubén Fedriani +14
Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…

Aislinn C. Plante, John J. Tobin, Patrick D. Sheehan +5
We present new ALMA 0.9 mm and VLA 9 mm observations in the Taurus Molecular Cloud (TMC) of 25 protostellar systems, containing 40 protostars, observed at 0.3" (~20 au) resolution.…
JWST-DECO: Temporal Variations in the Mid-IR Silicate Features of Two T Tauri Discs Based on Spitzer and JWST observations
N. Sameshima, T. Miyata, T. Kamizuka +9
Mid-infrared spectra of planet-forming discs commonly show prominent silicate emission, whose spectral shape is sensitive to the disc temperature distribution as well as its minera…
Extensive Observational Evidence for Massive Star Stellar Wind Variability at Low Metallicities: implications for mass-loss rate determination
Timothy N. Parsons, Raman K. Prinja, Derck L. Massa +1
Mass-loss from massive stars is fundamental to stellar and galactic evolution and enrichment of the interstellar medium. Reliable determination of mass-loss rate is dependent upon…
Citizen CATE 2024: Extending Totality During the 8 April 2024 Total Solar Eclipse with a Distributed Network of Community Participants
Sarah A. Kovac, Amir Caspi, Daniel B. Seaton +240
The Citizen CATE 2024 next-generation experiment placed 43 identical telescope and camera setups along the path of totality during the total solar eclipse (TSE) on 8 April 2024 to…
Observation of undepleted phosphine in the atmosphere of a low-temperature brown dwarf
Adam J. Burgasser, Eileen C. Gonzales, Samuel A. Beiler +16
The atmospheres of low-temperature brown dwarfs and gas giant planets are expected to contain the phosphine molecule, PH However, previous observations have shown much lower ab…
A star-by-star correspondence between X-ray activity and rotation in the young open cluster NGC 2516 with eROSITA
Dario J. Fritzewski, Sydney A. Barnes, Samet Ok +2
The coronal soft X-ray emission of cool stars, especially when taken in combination with their measured rotation periods, offers insights into their levels of magnetic activity and…
Dynamical mass of the Serpens intermediate-mass young stellar system EC\,95 with DYNAMO--VLBA
Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8
We present dynamical mass measurements, obtained from multi-epoch Very Long Baseline Interferometry (VLBI) observations, for the young multiple stellar system EC\,95, located in th…
Asteroseismic Study of Subgiants and Giants of the Open Cluster M67 using Kepler/K2: Expanded Sample and Precise Masses
Claudia Reyes, Dennis Stello, Marc Hon +7
Sparked by the asteroseismic space revolution, ensemble studies have been used to produce empirical relations linking observed seismic properties and fundamental stellar properties…
OGLE-2002-BLG-360: a dusty anomaly among red nova remnants
T. Steinmetz, T. Kamiński, C. Melis +4
OGLE-2002-BLG-360 is an example of a Galactic red nova, the aftermath of a non-compact stellar merger. The dusty nature of the circumstellar environment makes observations of this…
The past, present and future of observations of externally irradiated disks
Planet formation environments collaboration, Megan Allen, Rossella Anania +51
Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolutio…
Oxygen Isotope Ratios in Hydrogen-Deficient Carbon Stars: A Correlation with Effective Temperature and Implications for White Dwarf Merger Outcomes
Advait Mehla, Mansi M. Kasliwal, Viraj Karambelkar +5
Hydrogen-deficient Carbon (HdC) stars are a class of supergiants with anomalous chemical compositions, suggesting that they are remnants of CO-He white dwarf (WD) mergers. This cla…
A tell-tale tracer for externally irradiated protoplanetary disks: comparing the [CI] 8727 A line and ALMA observations in proplyds
Mari-Liis Aru, Karina Mauco, Carlo F. Manara +15
The evolution of protoplanetary disks in regions with massive OB stars is influenced by externally driven winds that deplete the outer parts of disks. These winds have previously b…
Isochrone fitting to the open cluster M67 in the era of Gaia and improved model physics
Claudia Reyes, Dennis Stello, Marc Hon +3
The Gaia mission has provided highly accurate observations that have significantly reduced the scatter in the colour-magnitude diagrams of open clusters. As a result of the improve…
An extended and refined grid of 3D STAGGER model atmospheres. Processed snapshots for stellar spectroscopy
Luisa F. Rodríguez Díaz, Cis Lagae, Anish M. Amarsi +6
Context: Traditional one-dimensional (1D) hydrostatic model atmospheres introduce systematic modelling errors into spectroscopic analyses of FGK-type stars. Aims: We present an upd…
