Disentangling the origin of chemical differences using GHOST

C. Saffe, P. Miquelarena, J. Alacoria +8

Aims. We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD 138202 + CD-30 12303. For the first time, we suggest ho…

Are Am stars and hot-Jupiter planets related?

C. Saffe, J. Alacoria, P. Miquelarena +8

Am stars are often components of short-period binary systems, where tidal interactions would result in low rotational velocities and help to develop the chemical peculiarities obse…

Gemini-GRACES high-quality spectra of Kepler evolved stars with transiting planets I. Detailed characterization of multi-planet systems Kepler-278 and Kepler-391

E. Jofré, J. M. Almenara, R. Petrucci +10

(abridged) Kepler-278 and Kepler-391 are two of the three evolved stars known to date on the RGB to host multiple short-period transiting planets. Moreover, these planets are among…

Signatures of rocky planet engulfment in HAT-P-4. Implications for chemical tagging studies

C. Saffe, E. Jofré, E. Martioli +3

Aims. To explore the possible chemical signature of planet formation in the binary system HAT-P-4, by studying abundance vs condensation temperature Tc trends. The star HAT-P-4 hos…

Kepler Observations of Very Low-Mass Stars

E. L. Martín, J. Cabrera, E. Martioli +2

Observations of very low-mass stars with Kepler represent an excellent opportunity to search for planetary transits and to characterize optical photometric variability at the cool…
