Recurrent Objects Programme

Courtesy Dr. Andrew Beardmore, University of Leicester

The Recurrent Objects Programme was initially set up by Guy Hurst of 'The Astronomer' organisation in the 1980's specifically to monitor poorly studied eruptive stars of various types, where outbursts generally occur at periods greater than one year, and/or where few or no observations of the object had been secured.    Many of the objects on the programme have no known period, and details of maximum and minimum brightness are rather uncertain.  I took over as co-ordinator of the ROP in 1990, and integrated it into the BAAVSS Main Programme in 1995, during my time as Director of the BAA Variable Star Section.

The main aims of the programme are...

To  monitor for outbursts or unusual behaviour either visually or with CCD's, in order to determine an outburst cycle, and with the help of CCD photometry, the orbital period.  

To obtain high quality photometry during outburst.

To raise the profile of the objects on the programme in order that greater observational coverage will be obtained.

To provide Professional astronomers with much needed data on these stars.

At present there are 79 objects on the programme (see below).  Most are Dwarf Novae, but several Novae have been included where more than one outburst has been detected, or is suspected of being recurrent from professional literature.  Other interesting NL objects appear too!

The latest and most up to date charts and sequences should be used whenever possible.  These are available from the AAVSO  web site, or the Arne Henden sequence pages for Henden/Sumner/Simonsen charts.  For charts in the BAAVSS format, contact the BAAVSS chart secretary John Toone for details.

Telephone alerts are welcomed for outbursts of any of these objects (and indeed for any variable star).  My telephone number is available throughout the night for such alerts.  Please send me an e-mail stating your interest in the ROP, and I will be happy to mail you my number.  Alternatively it can be found on the back cover of the VSS Circulars.
