Context. The seismic data obtained by CoRoT for the star HD 49933 enable us for the first time to measure directly the amplitudes and linewidths of solar-like oscillations for a star other than the Sun. From those measurements it is possible, as was done for the Sun, to constrain models of the excitation of acoustic modes by turbulent convection. Aims. We compare a stochastic excitation model described in Paper I with the asteroseismology data for HD 49933, a star that is rather metal poor and…

The solar-like CoRoT ? target HD 170987: spectroscopic and seismic observations
Context. The CoRoT mission is in its third year of observation and the data from the second long run in the galactic centre direction are being analysed. The solar-like oscillating stars that have
Amplitudes of solar-like oscillations in red giant stars - Evidence for non-adiabatic effects using CoRoT observations
Context. A growing number of solar-like oscillations has been detected in red giant stars thanks to the CoRoT and Kepler space-crafts. In the same way as for main-sequence stars, mode driving is
Amplitude and lifetime of radial modes in red giant star spectra observed by Kepler
Context. The space-borne missions CoRoT and Kepler have provided photometric observations of unprecedented quality. The study of solar-like oscillations observed in red giant stars by these
Pulsation spectrum of δ Scuti stars: the binary HD 50870 as seen with CoRoT and HARPS
Aims. We present the results obtained with the CoRoT satellite for HD 50870, a δ Sct star which was observed for 114.4 d. The aim of these observations was to evaluate the results obtained for HD
Starting in 2014 December, Kepler K2 observed Neptune continuously for 49 days at a 1 minute cadence. The goals consisted of studying its atmospheric dynamics, detecting its global acoustic
Stellar granulation as seen in disk-integrated intensity. II. Theoretical scaling relations compared with observations
Context. A large set of stars observed by CoRoT and Kepler shows clear evidence for the presence of a stellar background, which is interpreted to arise from surface convection, i.e., granulation.
Stochastic excitation of acoustic modes in stars
For more than ten years, solar-like oscillations have been detected and frequencies measured for a growing number of stars with various characteristics (e.g. different evolutionary stages, effective
Stellar oscillations. II The non-adiabatic case
A leap forward has been performed due to the space-borne missions, MOST, CoRoT and Kepler. They provided a wealth of observational data, and more precisely oscillation spectra, which have been (and
Asteroseismology of Red Giants from the First Four Months of Kepler Data: Global Oscillation Parameters for 800 Stars
We have studied solar-like oscillations in ∼800 red giant stars using Kepler long-cadence photometry. The sample includes stars ranging in evolution from the lower part of the red giant branch to the
A Bayesian approach to scaling relations for amplitudes of solar-like oscillations in Kepler stars
We investigate dierent amplitude scaling relations adopted for the asteroseismology of stars that show solar-like oscillations. Amplitudes are among the most challenging asteroseismic quantities to


A fresh look at the seismic spectrum of HD49933: analysis of 180 days of CoRoT photometry
Context. Solar-like oscillations have now been observed in several stars, thanks to ground-based spectroscopic observations and space-borne photometry. CoRoT, which has been in orbit since December
The CoRoT target HD 49933 - I. Effect of the metal abundance on the mode excitation rates
Context. Solar-like oscillations are stochastically excited by turbulent convection at the surface layers of the stars. Aims. We study the role of the surface metal abundance on the efficiency of the
