Small-Scale Magnetic Fields of Hyades M Dwarfs: Evolution with Age from the Pleiades to Field Stars
Fábio Wanderley, Katia Cunha, Oleg Kochukhov +9
Small-scale magnetic fields are derived for 18 M-dwarf stars in the Hyades open cluster through an analysis of Zeeman broadening in magnetically sensitive lines from the APOGEE spe…
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…
Chemical Abundances of the Bioessential Elements C, O and S, and the Refractory Elements Fe and Ni, in Solar-type Exoplanet-hosting Stars from HARPS North and South
E. Costa-Almeida, L. Ghezzi, K. Cunha +2
We determined atmospheric and evolutionary parameters, along with chemical abundances of C, O, S, Fe, and Ni for 290 solar-type exoplanet hosting stars using high-resolution HARPS-…
A Chemical Mismatch Between Young Stars and Their Inner Disks
Diogo Souto, Ilaria Pascucci, Katia Cunha +1
We present the first stellar elemental abundance study for two very low-mass stars, similar in mass to TRAPPIST-1, in the \,Myr-old Upper-Sco association. Their mid-infra…
