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…
A Probabilistic Framework for Population Studies of the Solar Neighborhood: Application to SDSS-V and Gaia
Ilija Medan, Keivan G. Stassun, Zachary Way +8
Studies of the Solar Neighborhood require spectroscopic follow-up of stars identified in astrometric surveys to fully characterize their physical properties. The SDSS-V Solar Neigh…
Magnetic fields in Massive Star-Forming Regions (MagMaR). VIII. Magnetic field overrun by gravity in GGD 27's accretion streamers
M. Fernández-López, J. A. López-Vázquez, J. M. Girart +20
Context. Accretion streamers connected to protostellar disks and/or envelopes are thought to transport material across several thousand of au. Whether the motions of the gas compri…
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…
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…
MINDS survey of silicates in T Tauri disks: Correlation between dust and gas
J. Varga, Th. Henning, L. B. F. M. Waters +20
Context. Silicates are key constituents of planet-forming disks and major building blocks of rocky planets. Mid-infrared spectral features of micron-sized silicate grains trace gra…
Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
X-Shooter survey of disk accretion in Upper Scorpius II. A lack of correlation between accretion rates and disk properties
A. Empey, C. F. Manara, R. Garcia Lopez +19
The evolution of protoplanetary discs is intertwined with the process of planet formation, growth and migration. Studies of nearby star forming regions of different ages and proper…
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…
A Minute-Cadence Deep Bulge Survey: First Data Release of DREAMS
Hongjing Yang, Weicheng Zang, Francisco Valdes +31
The DECam Rogue Earths and Mars Survey (DREAMS), a NOIRLab survey program, has been conducting a three-year survey covering a 5 deg area in the Galactic bulge (roughly spanning…
The CARMENES search for exoplanets around M dwarfs. A homogeneous catalogue of projected rotational velocities accounting for limb-darkening
R. Varas, G. Morello, M. Zechmeister +18
Stellar rotation is closely linked to both age and magnetic activity. Through gyrochronology, it provides a means to estimate stellar ages and trace the evolution of planetary syst…
Isochrone-cloud fitting and asteroseismology of the Kepler open cluster NGC6866
Haotian Wang, Gang Li, Dario J. Fritzewski +2
We investigate how isochrones computed with different input physics and initial conditions affect the age dating of the open cluster NGC 6866, and compare the results with asterose…
Unlocking accretion rate diagnostics for high-mass protostars using JWST/MIRI HI lines
S. D. Reyes-Reyes, H. Beuther, E. F. van Dishoeck +14
While many aspects of high-mass star formation have been investigated, the accretion onto the central protostars is one of the most fundamental but less explored physical propertie…
Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou
L. Drouglazet, E. Alecian, A. Sousa +27
Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…
PRODIGE -- envelope to disk with NOEMA VIII. Sulfur oxides trace a shock caused by a streamer in the inner envelope of a protostar
María Teresa Valdivia-Mena, Jaime E. Pineda, Caroline Gieser +24
(Abridged) Recently, streamers have been observed causing shocks at the outer edge of protoplanetary disks. The study of sulfur-bearing species can help us to understand the physic…
The sensitivity and behaviour of the curvature in the échelle diagram of red-giant stars
S. Hekker, Y. Elsworth, S. Basu +5
In the convective envelopes of relatively cool stars, oscillations are excited by turbulent convection. In these so-called solar-like oscillators, radial oscillation modes appear a…
