Software tool for automatic detection of solar plages in the Coimbra Observatory spectroheliograms
T. Barata, S. Carvalho, I. Dorotovic +4
Full-disk spectroheliograms have been taken in Coimbra on a daily basis since 1926 in the Ca II K-line (K1 and K3). Later, in 1989, with the upgrade of the equipment it was possibl…
Application of Neural Networks to the study of stellar model solutions
F. J. G. Pinheiro, T. Simas, J. Fernandes +1
Artificial neural networks (ANN) have different applications in Astronomy, including data reduction and data mining. In this work we propose the use ANNs in the identification of s…
Constraints of a pulsation frequency on stellar parameters in the eclipsing spectroscopic binary system: V577 Oph
O. L. Creevey, J. Telting, J. A. Blemonte +7
We present a preliminary spectroscopic analysis of the binary system V577Oph, observed during the summer of 2007 on the 2.6m NOT telescope on La Palma. We have obtained time series…
The universal red-giant oscillation pattern; an automated determination with CoRoT data
B. Mosser, K. Belkacem, M. J. Goupil +12
The CoRoT and Kepler satellites have provided thousands of red-giant oscillation spectra. The analysis of these spectra requires efficient methods for identifying all eigenmode par…
Multisite observations of the PMS delta Scuti star V351 Ori
V. Ripepi, M. Marconi, S. Bernabei +12
We present the results of multisite observations spanning two years on the pre--main-sequence (PMS) star V351 Ori. A total of around 180 hours of observations over 29 nights have b…
