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…
Diagnosing pulsar winds in black-widow, redback, and other binary millisecond pulsar systems
Anne Zilles, Kumiko Kotera, Rene Rohrmann +1
Binary systems composed of a recycled millisecond pulsar and a stellar companion in close orbit could be excellent sites to diagnose pulsar winds. In such systems, the pulsar outfl…
Analysis of a long-duration AR throughout five solar rotations: Magnetic properties and ejective events
Francisco A. Iglesias, Hebe Cremades, Luciano A. Merenda +4
Coronal mass ejections (CMEs), which are among the most magnificent solar eruptions, are a major driver of space weather and can thus affect diverse human technologies. Different p…
The active RS CVn-type system SZ Pictoris
C. I. Martínez, J. F. González, A. Buccino +2
We study the short and long-term variability of the spectroscopic binary SZ Pictoris, a southern RS CVn-type system. We used mid-resolution echelle spectra obtained at CASLEO spann…
A Reverse Shock in GRB 181201A
Tanmoy Laskar, Hendrik van Eerten, Patricia Schady +26
We present comprehensive multiwavelength radio to X-ray observations of GRB 181201A spanning from s to days after the burst, comprising the first joint AL…
Ross 128 -- GL 447A possible activity cycle for a slow-rotating fully-convective star
Ibanez Bustos, R. V., Buccino +5
Context. Long-term chromospheric activity in slow-rotating fully-convective stars has been scarcely explored. Ross 128 (Gl 447) is a slow-rotator and inactive dM4 star which has be…
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…
First long-term activity study of AU Microscopii: a possible chromospheric cycle
R. V. Ibañez, A. P. Buccino, M. Flores +4
M stars are ideal targets to search for Earth-like planets. However, they usually have high levels of magnetic activity, which could affect their habitability and make difficult th…
