Activity cycles in RS CVn type stars

C. I. Martínez, P. J. D. Mauas, A. P. Buccino

We compile a list of 121 RS CVn type stars from the bibliography in southern hemisphere, to search for activity cycles, covering a large range of luminosities and rotation periods.…

The peculiar chemical pattern of the WASP-160 binary system: signatures of planetary formation and evolution?

Emiliano Jofré, Romina Petrucci, Yilen Gómez Maqueo Chew +8

Wide binary stars with similar components hosting planets provide a favorable opportunity for exploring the star-planet chemical connection. We perform a detailed characterization…

Fundamental parameters of the eclipsing binary DD CMa and evidence for mass exchange

J. A. Rosales, R. E. Mennickent, G. Djurašević +5

We present a detailed photometric and spectroscopic analysis of DD CMa, based on published survey photometry and new spectroscopic data. We find an improved orbital period of $P_\m…

Constraints on planetesimal accretion inferred from particle-size distribution in CO chondrites

Gabriel A. Pinto, Yves Marrocchi, Alessandro Morbidelli +5

The formation of planetesimals was a key step in the assemblage of planetary bodies, yet many aspects of their formation remain poorly constrained. Notably, the mechanism by which…

Searching for new solar twins: The Inti survey for the Northern Sky

J. Y. Galarza, R. López-Valdivia, D. Lorenzo-Oliveira +9

Solar twins are key in different areas of astrophysics, however only just over a hundred were identified and well-studied in the last two decades. In this work, we take advantage o…

Chemical analysis of early-type stars with planets

C. Saffe, P. Miquelarena, J. Alacoria +6

Aims. To explore the chemical pattern of early-type stars with planets, searching for a possible signature of planet formation. In particular, we study a likely relation between th…
