The 2009 Outburst of V630 Cassiopeiae

TL;DR

This paper reports on the 2009 outburst of the unusual dwarf nova V630 Cassiopeiae, analyzing its duration, brightness, and outburst characteristics, which resemble those of similar long-period dwarf novae.

Contribution

It provides detailed observational data on the rare 2009 outburst of V630 Cas, including its duration, light curve, and classification as an inside-out outburst.

Findings

Outburst lasted about 104 days

Maximum brightness reached V=14.0

Outburst characteristics similar to other long-period dwarf novae

Abstract

We present observations and analysis of the 2009 outburst of the unusual dwarf nova V630 Cas which is only the third recorded outburst of this star. The outburst lasted about 104 days, with the rise to maximum being slightly slower than the decline, which we interpret as an inside-out outburst. At is brightest it had V = 14.0, 2.3 magnitudes above the mean quiescence magnitude. The characteristics of the outburst are similar to several other long orbital period dwarf novae.
