The Sloan Extension for Galactic Understanding and Exploration 2 (SEGUE-2) obtained 128,288 low-resolution spectra (R ~ 1800) of 118,958 unique stars in the...
SEGUE: A Spectroscopic Survey of 240,000 Stars with g = 14-20
The Sloan Extension for Galactic Understanding and Exploration (SEGUE) Survey obtained ≈240,000 moderate-resolution (R ~ 1800) spectra from 3900 Å to 9000 Å of...
Seismic analysis of HD 43587Aa, a solar-like oscillator in a multiple system
Context. The object HD 43587Aa is a G0V star observed during the 145-day LRa03 run of the COnvection, ROtation and planetary Transits space mission (CoRoT), for...
Seismic and spectroscopic analysis of nine bright red giants observed by Kepler
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...
Seismic and spectroscopic characterization of the solar-like pulsating CoRoT target HD 49385
Context. The star HD 49385 is the first G-type solar-like pulsator observed in the seismology field of the space telescope CoRoT. The satellite collected 137...
Seismic constraints on rotation of Sun-like star and mass of exoplanet
Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of...
Seismic constraints on the radial dependence of the internal rotation profiles of six Kepler subgiants and young red giants
Context. We still do not understand which physical mechanisms are responsible for the transport of angular momentum inside stars. The recent detection of mixed...
Seismic differences between solar magnetic cycles 23 and 24 for low-degree modes
Solar magnetic activity follows regular cycles of about 11 years with an inversion of polarity in the poles every ∼22 years. This changing surface magnetism...
Seismic Evidence for a Rapidly Rotating Core in a Lower-giant-branch Star Observed with Kepler
Rotation is expected to have an important influence on the structure and the evolution of stars. However, the mechanisms of angular momentum transport in stars...
