Thorium in solar twins: implications for habitability in rocky planets
Rafael B. Botelho, Andre de C. Milone, Jorge Melendez +10
We have investigated the thorium (Th) abundance in a sample of 53 thin disc solar twins covering a wide range of ages. These data provide constrains on the mantle energy budget of…
The Solar Twin Planet Search. I. Fundamental parameters of the stellar sample
I. Ramirez, J. Melendez, J. Bean +10
We are carrying out a search for planets around a sample of solar twin stars using the HARPS spectrograph. The goal of this project is to exploit the advantage offered by solar twi…
Distance Scale Zero-Points from Galactic RR Lyrae Star Parallaxes
G. Fritz Benedict, Barbara E. McArthur, Michael W. Feast +15
We present new absolute trigonometric parallaxes and proper motions for seven Pop II variable stars: five RR Lyr variables; RZ Cep, XZ Cyg, SU Dra, RR Lyr, UV Oct; and two type 2 C…
