A Catalog of Homogeneously Derived Stellar Parameters for Spectroscopic Survey Stars

Stefan Y. Stefanov, Evelina Zaharieva, Djemma Ruseva +9

Uniformly derived stellar parameters are vital for exoplanet demographic studies because they directly influence the inferred planetary masses, radii, and bulk densities. This stud…

Deep MUSE observations of SNR 0509-67.5 reveal a double degenerate merger progenitor

Priyam Das, Ivo R. Seitenzahl, Gilles Ferrand +5

Deep MUSE observations of SNR 0509-67.5 reveal that the coronal [Fe\,\textsc{xiv}] 5303 emission line appears with either one or two velocity components across the entire…

Physics of Eclipsing Binaries. VI. Hot, compact stars

David Jones, Nicole Reindl, Kyle Conroy +9

Models of eclipsing binaries require the assignment of appropriate emergent intensities to the surface elements of the binary components. For distance-dependent modelling of flux-c…

Revealing α-Element's Past with Subaru/IRD: Oxygen Abundance of 35 Very Metal-Poor Stars from Near-IR OH lines

Bakuh Danang Setyo Budi, Wako Aoki, Nicholas Storm +10

Oxygen abundances in very and extremely metal-poor (V/EMP) stars provide critical constraints on early massive stars' nucleosynthesis. An Oxygen abundance analysis is presented for…

The role of mass transfer efficiency in stability criteria: Implementation in SEVN and a test on blue stragglers and binary compact objects

M. Echeveste, G. J. Escobar, G. Iorio +12

Context: The stability of mass transfer through Roche-lobe overflow plays a key role in shaping the outcome of binary interactions. However, the criterion for mass transfer stabili…

Orbital motion and dynamical mass of the complex periodic variable binary system 2MASS J05082729-2101444

S. Curiel, G. N. Ortiz-León, V. J. S. Béjar +22

We used very long baseline interferometry to constrain the orbit of the binary system 2MASS J05082729-2101444. We observed the system with the VLBA in three epochs at a frequency o…
