B, V, and R photometry obtained during the first observed outburst of HS 0907+1902 (V approximate to 13) reveals deep eclipses (Delta V approximate to 2.1 - 2.8) and an orbital period P(orb) = 4.2 h with the eclipse depth decreasing to the red. The outburst eclipse profiles are symmetric, indicating an axisymmetrical brightness distribution in the accretion disc. We derive an inclination i approximate to 73 degrees - 79 degrees from the eclipse duration. The quiescent spectrum obtained with the Hobby-Eberly Telescope shows double peaked emission lines of H I, He I and Fe I,II and clearly identifies the system as a dwarf nova. Absorption features of the secondary star are detected at red wavelengths from which a spectral class M3 +/- 1.5 and a distance of d = 320 +/- 100 pc are derived."],["dc.identifier.isi","000087446700005"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/45601"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0004-6361"],["dc.title","HS 0907+1902: a new 4.2 hr eclipsing dwarf nova"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

During a long outburst with a duration of similar to 12 days, we detected superhumps with a period of 0.(d)0601(5), revealing that this star is an SU UMa star. A short outburst which lasted 3 days was found about 40 days after the onset of the superoutburst. From quiescence observations, we determine an orbital period of 0.(d)05898(2). The small outburst amplitude of similar to3.5 mag, the short orbital period, and the normal outburst cycle length suggest that HS 1449+6415 is an intermediate object between ER UMa stars with high mass-transfer rates and WZ Sge stars with Very low mass-transfer rates."],["dc.identifier.isi","000166998400045"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/31757"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1432-0746"],["dc.relation.issn","0004-6361"],["dc.title","A newly discovered SU UMa-type dwarf nova, HS 1449+6415"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
