A Multi-instrument Generalized Lomb-Scargle Periodogram Implementation
Giulia Martos, Néstor Espinoza, Jorge Meléndez
We present an implementation of the well-known and broadly used Generalized Lomb-Scargle Periodogram (GLS) which simultaneously takes into account individual offsets introduced in…
Detailed spectroscopic and photometric analysis of the remarkable planet-hosting wide binary system HD 202772A/B
Emiliano Jofré, Yilen Gómez Maqueo Chew, Romina Petrucci +15
We conducted a detailed spectroscopic and photometric characterization of the planet-hosting wide binary HD 202772A/B. No planet has been detected around HD 202772B, whereas HD 202…
A New Age-Activity Relation For Solar Analogs that Accounts for Metallicity
Gabriela Carvalho-Silva, Jorge Meléndez, Anne Rathsam +5
Determining stellar ages is challenging, particularly for cooler main-sequence stars. Magnetic evolution offers an observational alternative for age estimation via the age-chromosp…
Stellar Characterization and a Chromospheric Activity Analysis of a K2 Sample of Planet-Hosting Stars
V. Loaiza-Tacuri, Katia Cunha, Verne V. Smith +4
Effective temperatures, surface gravities, and iron abundances were derived for 109 stars observed by the K2 mission using equivalent width measurements of Fe I and Fe II lines. Ca…
Precise radial velocities of giant stars. III. Spectroscopic stellar parameters
S. Hekker, J. Meléndez
Context: A radial velocity survey of about 380 G and K giant stars is ongoing at Lick observatory. For each star we have a high signal to noise ratio template spectrum, which we us…
