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…
Wandering near the red edge: photometric observations of three cool ZZ Ceti stars
Zs. Bognár, M. Paparó, Á. Sódor +11
We summarize our findings on three cool ZZ Ceti type pulsating white dwarfs. We determined eight independent modes in HS 0733+4119, of which seven are new findings. For GD 154, we…
Asteroseismology of the ZZ Ceti star KUV 08368+4026
C. Li, J. -N. Fu, G. Vauclair +5
Asteroseismology is a unique tool to explore the internal structure of stars through both observational and theoretical research. The internal structure of pulsating hydrogen shell…
Infrared excesses in stars with and without planets using revised photometry
Raul F. Maldonado, Miguel Chavez, Emanuele Bertone +1
We present an analysis on the potential prevalence of mid infrared excesses in stars with and without planetary companions. Based on an extended database of stars detected with the…
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…
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…
