29 Mar 2006 | Abstract: | We continue our programme of extended single-site observations of pulsting subdwarf B (sdB) stars and present the results of extensive time series photometry to resolve the pulsation spectra for use in asteroseismological analyses. PG 0154+182, HS 1824+5745, and HS 2151+0857 were observed at the MDM Observatory during 2004 and 2005. Our observations are sufficient to resolve the pulsations of all three target stars. We extend the number of known frequencies for PG 0154+182 from one to six, confirm that HS 1824+5745 is a mono-periodic pulsator, and extend the number of known frequencies to five for HS 2151+0857. We perform standard tests to search for multiplet structure, measure amplitude variations as pertains to stochastic excitation, and examine the mode density to constrain the mode degree l. | Source: | arXiv, astro-ph/0603804 | Services: | Forum | Review | PDF | Favorites |
