Pulsating sdB stars (also known as EC 14026 stars) offer the chance to gain new insights into the formation and evolution of extreme Horizontal Branch stars using the tools of asteroseismology. PG1605+072 is an outstanding object in its class, with the richest frequency spectrum, the longest periods, and the largest variations. The MSST campaign took place in May/June 2002 immediately following the Whole Earth Telescope Xcov22 run, which observed PG 1605+072 as an alternate target. We will first give an overview of the project and its feasibility, after which we will present the massive data set, made up of 399 h of photometry and 151 h of spectroscopy. The overall aims of the project are to examine light/velocity amplitude ratios and phase differences, changes in equivalent width/line index, and lambda-dependence of photometric amplitudes, and to use these properties for mode identification."],["dc.identifier.doi","10.1023/B:ASTR.0000044360.79737.38"],["dc.identifier.isi","000224389400041"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/49036"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Kluwer Academic Publ"],["dc.publisher.place","Dordrecht"],["dc.relation.conference","Meeting on sdB Stars"],["dc.relation.eventlocation","Keele Univ, Staffordshire, ENGLAND"],["dc.relation.issn","0004-640X"],["dc.title","MSST observations of the pulsating sdB star PG 1605+072"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

The oscillations are multiperiodic with periods between 0.8 and 1.4 hr (180-340 muHz) and semiamplitudes less than 0.2%. We also observe that the periods and amplitudes appear variable, making the pulsation structure of PG 1716 complicated. The periods are an order of magnitude longer than those seen in EC 14026 (sdBV) stars, implying that they are gravity modes rather than pressure modes. As such, they represent a new class of variable star."],["dc.identifier.doi","10.1086/383260"],["dc.identifier.isi","000221523900038"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/48308"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0004-637X"],["dc.title","Discovery of gravity-mode pulsators among subdwarf B stars: PG 1716+426, the class prototype"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
