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…
Stellar Parameters and Metallicities of Stars Hosting Jovian and Neptunian Mass Planets: A Possible Dependence of Planetary Mass on Metallicity
L. Ghezzi, K. Cunha, V. V. Smith +3
The metal content of planet hosting stars is an important ingredient which may affect the formation and evolution of planetary systems. Accurate stellar abundances require the dete…
The Homogeneous Study of Transiting Systems (HoSTS) I. The Pilot Study of WASP-13
Y. Gómez Maqueo Chew, F. Faedi, P. Cargile +13
We present the fundamental stellar and planetary properties of the transiting planetary system WASP-13 within the framework of the Homogeneous Study of Transiting Systems (HoSTS).…
The Bi-Canonical Degree of a Cohen-Macaulay Ring
L. Ghezzi, S. Goto, J. Hong +2
This paper is a sequel to [8] where we introduced an invariant, called canonical degree, of Cohen-Macaulay local rings that admit a canonical ideal. Here to each such ring with a c…
Detailed Abundances of the Solar Twins 16 Cygni A and B: Constraining Planet Formation Models
S. C. Schuler, K. Cunha, V. V. Smith +4
Results of a detailed abundance analysis of the solar twins 16 Cyg A and 16 Cyg B based on high-resolution, high signal-to-noise ratio echelle spectroscopy are presented. 16 Cyg B…
Emerging trends in metallicity and lithium properties of debris disc stars
C. Chavero, R. de la Reza, L. Ghezzi +5
Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently stu…
