Seismic signatures of magnetic activity in solar-type stars observed by Kepler
A. R. G. Santos, T. L. Campante, W. J. Chaplin +8
The properties of the acoustic modes are sensitive to magnetic activity. The unprecedented long-term Kepler photometry, thus, allows stellar magnetic cycles to be studied through a…
On the frequency dependence of p-mode frequency shifts induced by magnetic activity in Kepler solar-like stars
D. Salabert, C. Régulo, F. Pérez Hernández +1
The variations of the frequencies of the low-degree acoustic oscillations in the Sun induced by magnetic activity show a dependence with radial order. The frequency shifts are obse…
Helioseismic inferences of the solar cycles 23 and 24: GOLF and VIRGO observations
D. Salabert, R. A. Garcia, A. Jimenez
The Sun-as-a-star helioseismic spectrophotometer GOLF and photometer VIRGO instruments onboard the SoHO spacecraft are collecting high-quality, continuous data since April 1996. We…
Differences of the Solar Magnetic Activity Signature in Velocity and Intensity Helioseismic Observations
D. Salabert, R. A. Garcia, A. Jimenez
The high-quality, full-disk helioseismic observations continuously collected by the spectrophotometer GOLF and the three photometers VIRGO/SPMs onboard the SoHO spacecraft for 17 y…
Seismic analysis of four solar-like stars observed during more than eight months by Kepler
S. Mathur, T. L. Campante, R. Handberg +41
Having started science operations in May 2009, the Kepler photometer has been able to provide exquisite data of solar-like stars. Five out of the 42 stars observed continuously dur…
Investigating the properties of granulation in the red giants observed by Kepler
S. Mathur, S. Hekker, R. Trampedach +18
More than 1000 red giants have been observed by NASA/Kepler mission during a nearly continuous period of ~ 13 months. The resulting high-frequency resolution (< 0.03 muHz) allows u…
Signature of a magnetic activity cycle in HD49933 observed by CoRoT
R. A. Garcia, J. Ballot, S. Mathur +2
Solar-like stars with an external convective envelope can develop magnetic activity cycles under the interaction of con- vection, rotation and magnetic fields. Even in the Sun, the…
An automatic pipeline analysing solar-like oscillating targets tested on CoRoT and simulated data
S. Mathur, R. A. Garcia, C. Regulo +3
The launch of the Kepler mission on 7th March 2009 opened a new bright future for the search of extra-solar planets while a huge amount of stars will be observed leading to the opp…
Frequency shifts of the individual low-degree p modes during solar cycle 23 and its extended minimum
D. Salabert, R. A. Garcia, P. L. Palle +1
We study the response of the low-degree solar p-mode frequencies to the unusual extension of the minimum of solar surface activity since 2007. Helioseismic observations collected b…
Evidence of increasing acoustic emissivity at high frequency with solar cycle 23 in Sun-as-a-star observations
R. Simoniello, W. Finsterle, R. A. Garcia +2
We used long high-quality unresolved (Sun-as-a-star observations) data collected by GOLF and VIRGO instruments on board the ESA/NASA SOHO satellite to investigate the amplitude var…
The Sun as a Star: 13 years of SoHO
R. A. Garcia
The best known Solar oscillation-like star is the Sun. During the last 14 years, the ESA/NASA Solar and Heliospheric Observatory (SoHO) has been continuously observing this star fr…
