Detecting prolonged activity minima in binary stars. The case of Ret
M. Flores, M. Jaque Arancibia, R. V. Ibañez Bustos +7
Context. It is well known that from 1645 to 1715 solar activity was notably low and the number of sunspots was extremely reduced. This epoch is known as the Maunder Minimum (MM). T…
The Southern Photometric Local Universe Survey (S-PLUS): improved SEDs, morphologies and redshifts with 12 optical filters
C. Mendes de Oliveira, T. Ribeiro, W. Schoenell +142
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ~9300 deg^2 of the celestial sphere in twelve optical bands using a dedicated 0.8 m robotic telescope, the T80-So…
High-precision analysis of binary stars with planets. I. Searching for condensation temperature trends in the HD 106515 system
C. Saffe, E. Jofre, P. Miquelarena +4
We explore the probable chemical signature of planet formation in the remarkable binary system HD 106515. The A star hosts a massive long-period planet with 9 MJup detected by radi…
RAMSES II - RAMan Search for Extragalactic Symbiotic Stars. Project concept, commissioning, and early results from the science verification phase
R. Angeloni, D. R. Gonçalves, S. Akras +16
Symbiotic stars (SySts) are long-period interacting binaries composed of a hot compact star, an evolved giant star, and a tangled network of gas and dust nebulae. They represent un…
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…
HD 38858: a solar type star with a 10.8 yr activity cycle. Searching for Balmer and metallic line variations
M. Flores, J. F. González, M. Jaque Arancibia +5
Context. The detection of chromospheric activity cycles in solar-analogue and twin stars, can be used to put in context the solar cycle. However, there is a relatively low percenta…
