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…
High-contrast imaging of HD 29992 and HD 196385 with GPI
Luciano H. García, R. Petrucci, E. Jofré +1
Based on high contrast images obtained with the Gemini Planet Imager (GPI), we report the discovery of two point-like sources at angular separations of and $ρ\sim0.80…
Using non-solar-scaled opacities to derive stellar parameters. Toward high-precision parameters and abundances
C. Saffe, M. Flores, P. Miquelarena +5
We implemented non-solar-scaled opacities in a simultaneous derivation of fundamental parameters and abundances. We carried out a high-precision stellar parameters and abundance de…
Testing the Planet-Metallicity Correlation in M-dwarfs with Gemini GNIRS Spectra
M. J. Hobson, E. Jofré, L. García +2
While the planet-metallicity correlation for FGK main-sequence stars hosting giant planets is well established, the results are not so clear for M-dwarf stars, for which precise me…
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…
The beta Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
S. Messina, M. Millward, A. Buccino +19
We intended to compile the most complete catalog of bona fide members and candidate members of the beta Pictoris association, and to measure their rotation periods and basic proper…
