Ultra-low Amplitude Variables in the Lmc – Classical Cepheids, Pop. Ii Cepheids, Rv Tau Stars and Binary Variables
A search for variable stars with ultra-low amplitudes (ULA), in the millimag range, has been made in the combined MACHO and OGLE data bases in the broad vicinity of the Cepheid instability strip in the HR diagram. A total of 25 singly periodic and 4 multiply periodic ULA objects has been uncovered. Our analysis does not allow us to distinguish between pulsational and ellipsoidal (binary) variab...
متن کاملIdentification and photometry of globular clusters in M 31 and M 33 galaxies
We have used the data from the DIRECT project to search for new globular cluster candidates in the M31 and M33 galaxies. We have found 67 new objects in M31 and 35 in M33 and confirmed 38 and 16 previously discovered ones. A V I and BV I photometry has been obtained for all the clusters in M31 and M33 respectively. Luminosity functions have been constructed for the clusters in each galaxy and c...
متن کاملBright metal - poor variables : why “ Anomalous ” Cepheids ?
We investigate the theoretical scenario concerning the large sample of variables recently discovered in the dwarf, metal-poor irregular galaxy Leo A, fo-cusing the attention on the " Anomalous " Cepheid phenomenon and its correlation with RR Lyrae stars, Classical and Population II Cepheids. To this purpose, we make use of suitable stellar and pulsation models to depict the pulsational history ...
متن کامل0 The DIRECT Project : Influence of Blending on the Cepheid Distance Scale . I . Cepheids in M 31
We investigate the influence of blending on the Cepheid distance scale. Blending is the close association of a Cepheid with one or more intrinsically luminous stars. High-resolution HST images are compared to our ground-based data, obtained as part of the DIRECT project, for a sample of 22 Cepheids in the M31 galaxy. The average (median) V -band flux contribution from luminous companions which ...
متن کاملObservations of M 31
As part of the Chandra GTO program we are monitoring and surveying M31 using the HRC and ACIS cameras. These observations have resolved the nuclear X-ray source into five separate sources, one of which is very soft and may (or may not!) be associated with the central super-massive black hole. In addition, the superb spatial resolution and low scattering of the Chandra telescope allows us to una...
