TV Corvi revisited: Precursor and superhump period derivative linked to the disk instability model
TV Corvi revisited: Precursor and superhump period derivative linked to the disk instability model
We report optical photometric observations of four superoutbursts of the short-period dwarf nova TV Crv. This object experiences two types of superoutbursts; one with a precursor and the other without. The superhump period and period excess of TV Crv are accurately determined to be d and , respectively. This large …
