A Test of FeH Line Parameters using DR19 APOGEE spectra of Benchmark M Dwarfs
Anderson Silva-Andrade, Diogo Souto, Katia Cunha +9
Recent studies have suggested a mismatch of up to 0.20 dex between iron abundances derived from Fe I and FeH lines in the H-band spectra of M dwarfs, and in this work we investigat…
Revisiting the Constancy of the Speed of Light: Galaxy Cluster Mass Bias Implications
R. F. L. Holanda, Marcelo Ferreira, Javier E. Gonzalez +1
In recent years, improvements in galaxy cluster observations have enabled a variety of tests of fundamental physics using these systems. In this work, we test the constancy of the…
Shadow of a Noncommutative Thin-Shell Gravastar
M. A. Anacleto, A. T. N. Silva, L. Casarini
One of the main challenges in astronomy is the direct observation of black holes. However, distinguishing black holes from ultra-compact horizonless objects through photon observat…
Chemical radial gradients for the bulge-bar stellar populations from the APOGEE survey
J. V. Sales-Silva, K. Cunha, V. V. Smith +20
The Milky Way bulge-bar is composed of multiple populations. Using chemical and kinematical planes, we segregate six populations in a bulge-bar sample observed by the APOGEE survey…
A Near-Infrared and Optical Study of NGC 5822: An Open Cluster Hosting Barium-stars and Lithium-Enriched Giant Stars
N. Holanda, V. Loaiza-Tacuri, A. Sonally +7
We present a chemical abundance study of giant stars in the Galactic open cluster NGC 5822, which hosts two barium stars (#002 and #201) and three lithium-enriched giants (#006, #1…
Modelling the Milky Way's exoplanet population based on cosmological galaxy simulations
Chloé Padois, Daniel del Ser, Friedrich Anders +7
In this paper we aim to simulate realistic exoplanet populations across different regions of the MW by combining state-of-the-art cosmological simulations of our Galaxy with exopla…
