ODUSSEAS: Upgraded version with new reference scale and parameter determinations for 82 planet-host M dwarf stars in SWEET-Cat
A. Antoniadis-Karnavas, S. G. Sousa, E. Delgado-Mena +2
Aims: Obtaining accurate derivations of stellar atmospheric parameters is crucial in the fields of stellar and exoplanet characterization. We present the upgraded version of our co…
The Metallicity-Period-Mass Diagram of low-mass exoplanets
S. G. Sousa, V. Adibekyan, N. C. Santos +14
The number of exoplanet detections continues to grow following the development of better instruments and missions. Key steps for the understanding of these worlds comes from their…
On the iron ionization balance of cool stars
M. Tsantaki, N. C. Santos, S. G. Sousa +3
High-resolution spectroscopic studies of solar-type stars have revealed higher iron abundances derived from singly ionized species compared to neutral, violating the ionization equ…
SWEET-Cat updated. New homogenous spectroscopic parameters
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14
Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
Measuring Stellar Atmospheric Parameters with ARES+MOOG
Sergio G. Sousa, Daniel T. Andreasen
The technical aspects in the use of an Equivalent Width (EW) method are described for the derivation of spectroscopic stellar parameters with ARES+MOOG. While the science descripti…
Atmospheric stellar parameters for large surveys using FASMA, a new spectral synthesis package
M. Tsantaki, D. T. Andreasen, G. D. C. Teixeira +4
In the era of vast spectroscopic surveys focusing on Galactic stellar populations, astronomers want to exploit the large quantity and good quality of data to derive their atmospher…
