A new method for extracting seismic indices and granulation parameters: Results for more than 20,000 CoRoT and Kepler red giants
Michel, E.; Samadi, R.; de Assis Peralta, R.
We have developed a new automated method intended to perform the simultaneous—and thus more consistent—measurement of both the seismic indices characterizing the oscillations and the parameters characterizing the granulation signature of red giant stars. This method, called MLEUP, takes advantage of the Maximum Likelihood Estimate (MLE) algorithm …
CoRoT data reduction by example
Weingrill, J.
Data reduction techniques published so far for the CoRoT N2 data product were targeted primarily on the detection of extrasolar planets. Since the whole dataset has been released, specific algorithms are required to process the lightcurves from CoRoT correctly. Though only unflagged datapoints must be chosen for scientific processing, some flags m…
A multiwavelength view of star-disk interaction in NGC 2264
Baglin, A.; Micela, G.; Stauffer, J. R. +2 more
Variability is a signature property of cool young stars, particularly for those surrounded by disks. Traditional single-band time series display complex features associated with accretion, disk structure, and accompanying stellar activity, but these processes are challenging to model. To make progress in connecting observed time domain properties …
Preliminary results on γ Dor and δ Sct-γ Dor hybrid s in the CoRoT exo-field of LRa01
Hareter, M.
The 131 days long, high-precision light curves observed in the CoRoT exo-field during LRa01 were investigated for γ Dor and δ Sct-γ Dor hybrid stars. In total 418 γ Dor and 274 δ Sct-γ Dor hybrid candidates were identified. For a fraction of these candidates spectra are available obtained at the Anglo-Australian Observatory. Effective temperatures…
