Seismic and spectroscopic analysis of 9 bright red giants observed by Kepler
H. R. Coelho, A. Miglio, T. Morel +21
Photometric time series gathered by space telescopes such as CoRoT and Kepler allow to detect solar-like oscillations in red-giant stars and to measure their global seismic constra…
Spectroscopic and asteroseismic analysis of the secondary clump red giant HD 226808
Bruno Lustosa De Moura, Paul G. Beck, Leandro de Almeida +5
In order to clarify the properties of the secondary clump star HD 226808 (KIC 5307747), we combined four years of data from Kepler space photometry with high-resolution spectroscop…
Lithium abundance and rotation of seismic solar analogues - Solar and stellar connection from Kepler and Hermes observations
P. G. Beck, J. -D. do Nascimento, T. Duarte +13
Lithium abundance A(Li) and surface rotation are good diagnostic tools to probe the internal mixing and angular momentum transfer in stars. We explore the relation between surface…
Probing seismic solar analogues through observations with the NASA Kepler space telescope and HERMES high-resolution spectrograph
P. G. Beck, D. Salabert, R. A. García +21
Stars similar to the Sun, known as solar analogues, provide an excellent opportunity to study the preceding and following evolutionary phases of our host star. The unprecedented qu…
Mass effect on the lithium abundance evolution of open clusters: Hyades, NGC 752, and M67
Matthieu Castro, Tharcísyo Duarte, Giancarlo Pace +1
Lithium abundances in open clusters provide an effective way of probing mixing processes in the interior of solar-type stars and convection is not the only mixing mechanism at work…
Theoretical evolution of Rossby number for solar analog stars
Matthieu Castro, Tharcísyo Duarte, José Dias do Nascimento
Magnetic fields of late-type stars are presumably generated by a dynamo mechanism at the interface layer between the radiative interior and the outer convective zone. The Rossby nu…
