Synthetic spectroscopic indices for identifying multiple stellar populations in globular clusters
Emanuele Bertone, Miguel Chávez, J. César Mendoza
We present an investigation of synthetic spectroscopic indices that can plausibly help in identifying the presence of multiple stellar populations in globular clusters. The study i…
The interaction of the halo around the butterfly planetary nebula NGC650-1 with the interstellar medium
G. Ramos-Larios, M. A. Guerrero, A. Nigoche-Netro +7
With its bright and wide equatorial waist seen almost edge-on (the butterfly body) and the faint and broad bipolar extensions (the butterfly wings), NGC650-1 is the archetypical ex…
Mg, Al, Si, Ca, Ti, Fe, and Ni abundance for a sample of solar analogues
Ricardo López-Valdivia, Emanuele Bertone, Miguel Chávez
We report on the determination of chemical abundances of 38 solar analogues, including 11 objects previously identified as super metal-rich stars. We have measured the equivalent w…
Deep GALEX UV Survey of the Kepler Field I: Point Source Catalog
Manuel Olmedo, James Lloyd, Eric E. Mamajek +4
We report observations of a deep near-ultraviolet (NUV) survey of the Kepler field made in 2012 with the Galaxy Evolution Explorer (GALEX) Complete All-Sky UV Survey Extension (CAU…
Lithium abundance in a sample of solar-like stars
R. López-Valdivia, J. B. Hernández-Águila, E. Bertone +3
We report on the determination of the lithium abundance [A(Li)] of 52 solar-like stars. For 41 objects the A(Li) here presented corresponds to the first measurement. We have measur…
Mg II h+k Flux - Rotational Period Correlation for G-type stars
Manuel Olmedo, Miguel Chávez, Emanuele Bertone +1
We present an analysis of the correlation between the mid-UV Mg II h and k emission lines and measured rotational periods of G-type stars. Based on IUE and HST high resolution spec…
