Detailed analysis of Balmer lines in cool dwarf stars
An analysis of Hα and Hβ spectra in a sample of 30 cool dwarf and subgiant stars is presented using MARCS model atmospheres based on the most recent...
Detailed Chemical Abundances for a Benchmark Sample of M Dwarfs from the APOGEE Survey
Individual chemical abundances for 14 elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M dwarfs using high...
Detailed chemical composition of the globular cluster Sextans A GC-1 on the outskirts of the Local Group
Context. The chemical composition of globular clusters (GCs) across the Local Group provides information on chemical abundance trends. Studying GCs in isolated...
Detailed chemical evolution models of the Tucana dSph galaxy
We use semi-analytical methods to obtain detailed chemical evolution models (CEMs) for the dwarf spheroidal (dSph) galaxy Tucana. Published star formation rates...
Detailed cool star flare morphology with CHEOPS and TESS***
Context. White-light stellar flares are proxies for some of the most energetic types of flares, but their triggering mechanism is still poorly understood. As...
Detailed Diagnostics of an X-Ray Flare in the Single Giant HR 9024
We analyze a 96 ks Chandra HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at...
Detailed Photometric Study of the Merging Group of Galaxies HCG 95
Results from Hα + continuum and Johnson UBVI imaging for HCG 95 are presented in order to study the star formation history of the galaxies in the group. Based...
Detailed spectrophotometric analysis of the superluminous and fast evolving SN 2019neq
SN 2019neq was a very fast evolving superluminous supernova. At a redshift z = 0.1059, its peak absolute magnitude was -21.5 ± 0.2 mag in g band. In this work...
