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…
Protective Effects of Halite to Vacuum and Vacuum-Ultraviolet Radiation: A Potential Scenario During a Young Sun Superflare
Ximena C. Abrevaya, Douglas Galante, Paula M. Tribelli +16
Halite (NaCl mineral) has exhibited the potential to preserve microorganisms for millions of years on Earth. This mineral was also identified on Mars and in meteorites. In this stu…
Accurate Atmospheric Parameters at Moderate Resolution Using Spectral Indices: Preliminary Application to the MARVELS Survey
Luan Ghezzi, Letícia Dutra-Ferreira, Diego Lorenzo-Oliveira +17
Studies of Galactic chemical and dynamical evolution in the solar neighborhood depend on the availability of precise atmospheric parameters (Teff, [Fe/H] and log g) for solar-type…
A Cautionary Tale: MARVELS Brown Dwarf Candidate Reveals Itself To Be A Very Long Period, Highly Eccentric Spectroscopic Stellar Binary
Claude E. Mack, Jian Ge, Rohit Deshpande +42
We report the discovery of a highly eccentric, double-lined spectroscopic binary star system (TYC 3010-1494-1), comprising two solar-type stars that we had initially identified as…
Very Low-mass Stellar and Substellar Companions to Solar-like Stars from MARVELS II: A Short-period Companion Orbiting an F Star with Evidence of a Stellar Tertiary And Significant Mutual Inclination
Scott W. Fleming, Jian Ge, Rory Barnes +59
We report the discovery via radial velocity of a short-period (P = 2.430420 \pm 0.000006 days) companion to the F-type main sequence star TYC 2930-00872-1. A long-term trend in the…
Astrobiologically Interesting Stars within 10 parsecs of the Sun
G. F. Porto de Mello, E. F. del Peloso, L. Ghezzi
The existence of life based on carbon chemistry and water oceans relies upon planetary properties, chiefly climate stability, and stellar properties, such as mass, age, metallicity…
