Insight into the Formation of Pic b through the Composition of Its Parent Protoplanetary Disk as Revealed by the Pic Moving Group Member HD 181327
Henrique Reggiani, Jhon Yana Galarza, Kevin C. Schlaufman +5
It has been suggested that Pic b has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star Pic and therefore the planet'…
The Chemical Composition of Extreme-Velocity Stars
Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman +5
Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use t…
Rocky planet engulfment in the binary system HIP 71726-37
J. Yana Galarza, R. López-Valdivia, J. Meléndez +1
Binary stars are supposed to be chemically homogeneous, as they are born from the same molecular cloud. However, high precision chemical abundances show that some binary systems di…
Rotation of solar analogs cross-matching Kepler and Gaia DR2
Jose-Dias do Nascimento, Leandro de Almeida, Eduardo Nunes Velloso +10
A major obstacle to interpreting the rotation period distribution for main-sequence stars from Kepler mission data has been the lack of precise evolutionary status for these object…
The Li-age correlation: the Sun is unusually Li deficient for its age
M. Carlos, J. Melendez, L. Spina +8
The present work aims to examine in detail the depletion of lithium in solar twins to better constrain stellar evolution models and investigate its possible connection with exoplan…
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…
