Abundances of planetary nebulae and evolved stars: Iron and sulfur depletion, and carbon and nitrogen enrichment, in low- and intermediate-mass stellar populations in the Milky Way

Letizia Stanghellini, Verne V. Smith, Katia Cunha +1

We explore the elemental abundances in Galactic planetary nebulae (PNe) compared with those of their stellar progenitors (Red Giant Branch and Asymptotic Giant Branch, RGB and AGB,…

Exploring new physics in the late Universe's expansion through non-parametric inference

Miguel A. Sabogal, Özgür Akarsu, Alexander Bonilla +2

In this study, we investigate deviations from the Planck-CDM model in the late universe () using the Gaussian Processes method, with minimal assumptions. Our goa…

Magnetic Fields of M Dwarfs from the Pleiades Open Cluster

Fabio Wanderley, Katia Cunha, Oleg Kochukhov +10

Average magnetic field measurements are presented for 62 M-dwarf members of the Pleiades open cluster, derived from Zeeman-enhanced Fe I lines in the H-band. An MCMC methodology wa…

SMARTY: The mileS Moderate resolution neAr-infRared sTellar librarY

Michele Bertoldo-Coêlho, Rogério Riffel, Marina Trevisan +13

Most of the observed galaxies cannot be resolved into individual stars and are studied through their integrated spectrum using simple stellar populations (SSPs) models, with stella…

Velocity Dispersion of the open cluster NGC 2571 by Radial Velocities and Proper Motions

Maxim V. Kulesh, Aleksandra E. Samirkhanova, Giovanni Carraro +3

We use a Kernel Density Estimator method to evaluate the stellar velocity dispersion in the open cluster NGC 2571. We derive the 3-D velocity dispersion using both proper motions a…

PEARLS: NuSTAR and XMM-Newton Extragalactic Survey of the JWST North Ecliptic Pole Time-Domain Field II

Xiurui Zhao, Francesca Civano, Christopher N. A. Willmer +30

We present the second NuSTAR and XMM-Newton extragalactic survey of the JWST North Ecliptic Pole (NEP) Time-Domain Field (TDF). The first NuSTAR NEP-TDF survey (Zhao et al. 2021) h…
