The SOL Project: Detailed characterization of candidates for the ZAMS and Subgiant stages
C. Eduardo-Oliveira S., L. Ghezzi, G. F. Porto de Mello +3
The context of the Sun in the galactic neighborhood is not well understood, especially when we compare its physical properties to those of nearby stars. Thereby, we still cannot fu…
Stellar characterization, Magnesium Abundances and Chromospheric Activity Analysis of Stars with Confirmed Exoplanets from the K2 mission
V. Loaiza-Tacuri, Diogo Souto, F. Quispe-Huaynasi +5
We present a homogeneous spectroscopic analysis of confirmed K2 mission exoplanet-hosting stars, comprising 301 targets with high-resolution optical spectra from HIRES and TRES tak…
Stellar Characterization and a Chromospheric Activity Analysis of a K2 Sample of Planet-Hosting Stars
V. Loaiza-Tacuri, Katia Cunha, Verne V. Smith +4
Effective temperatures, surface gravities, and iron abundances were derived for 109 stars observed by the K2 mission using equivalent width measurements of Fe I and Fe II lines. Ca…
M dwarf spectral indices at moderate resolution: accurate and [Fe/H] for 178 southern stars
E. Costa-Almeida, G. F. Porto de Mello, R. E. Giribaldi +2
We present a spectroscopic and photometric calibration to derive effective temperatures and metallicities [Fe/H] for M dwarfs, based on a Principal Component Ana…
