Probable nonradial g-mode pulsation in early A-type stars
E. Antonello, L. Mantegazza, M. Rainer +1
A survey for line profile variability in early A-type stars has been performed in order to detect nonradial pulsation signatures. The star HR 6139, with spectral type A2V and estim…
GAUDI: a preparatory archive for the COROT mission
E. Solano, C. Catala, R. Garrido +34
The GAUDI database (Ground-based Asteroseismology Uniform Database Interface, http://sdc.laeff.esa.es/gaudi/) is a preparatory archive for the COROT (COnvection, ROtation and plane…
The effects of blending on the light curve shape of Cepheids
E. Antonello
A short analysis is presented of the effects on the cepheid light curve shape, i.e. on the Fourier parameters usually adopted for its description, of the blending of the stellar im…
V39: an unusual object in the field of IC 1613
L. Mantegazza, E. Antonello, D. Fugazza +2
The variable star V39 in the field of IC 1613 is discussed in the light of the available photometric and new spectroscopic data. It has strong emission Balmer lines, and the observ…
Variable stars in nearby galaxies. VI. Frequency-period distribution of Cepheids in IC 1613 and other galaxies of the Local Group
E. Antonello, D. Fugazza, L. Mantegazza
The frequency--period distribution and other properties of Cepheids in IC 1613 are discussed and compared with those of stars in our Galaxy (Milky Way), LMC, SMC, M31 and M33. Taki…
Variable stars in nearby galaxies. II. Population I and II Cepheids in Field A of IC 1613
E. Antonello, L. Mantegazza, D. Fugazza +1
The light curves of Cepheids and other variable stars in Field A of IC 1613, obtained with a CCD and no filter ( photometry), have been analyzed. It is possible to separate fir…
