Eruptive variables

Eruptive variable stars show irregular or semi-regular brightness variations caused by material being lost from the star, or in some cases being accreted to it. Despite the name these are not explosive events, those are the cataclysmic variables.

Projects for eruptive variables

VSS runs a number of projects related to eruptive systems, which are outlined below.

V0745 Sco Campaign

Project Leader: Tom Richards

Rod Stubbings observed V745 Sco in outburst (mvis=9.0) on 2014 February 6.6 after observing it fainter than 13.0 24 hours prior. The nova has subsequently been confirmed by Paul Camilleri (CMQ) and Steve O’Connor (OCN), with more data coming in.

Jeno Sokoloski has requested as much photometry as possible and is also requesting spectroscopic follow-up from the community as well. Several professional researchers are already working on getting X-ray and radio data for this nova, and optical data from the AAVSO community will be very useful for comparison to other wavelengths.
