BAA VSS PROGRAMMES AND CHARTS

The Eclipsing Binary Programme

This catalogue (v6.4, PDF, 36kb) lists all of the stars on the Section's Eclipsing Binary Variable Star Programme . Charts for these stars can be ordered from the Eclipsing Binary Secretary except those charts listed as TA charts which can be obtained from the Editor of The Astronomer Magazine (http://www.theastronomer.org).

Alert stars are marked with an '*'. Please telephone Gary Poyner or the Director immediately for the following...

* Alert if in outburst.
** Alert if fading.

T/B means that the object is monitored as both a Telescopic and Binocular programme star.
R indicates that the object is part of the Recurrent Objects Program.

The following abbreviations are used in the 'Type' column:

BLLac BL Lac object
 
DQ DQ Her type object (Polar)
 
E Eclipsing binary [EA - Algol type, EB - Beta Lyr type, EW - W UMa type]
 
Gal Galaxy (with variable nucleus)
GCas Gamma Cas type eruptive variable
In  Irregular nebular variable [Ina - hot, Inb - cool]
L Red irregular pulsating variable [Lb - giant, Lc - supergiant]
M Mira type pulsating variable
N Nova [Na - fast, Nb - slow, Nc - very slow, Nr - recurrent]
NL Nova-like stars
QSO Quasi-stellar object (Quasar)
RCB R CrB type eruptive variable
RV RV Tau type pulsating variable [RVa - constant mean mag, RVb - varying mean mag]
 
SDor S Dor type eruptive variable
SR Semiregular pulsating variable [SRa - stable periodicity, SRb - loose periodicity, SRc - supergiant, SRd - yellow]
 
UG U Gem type cataclysmic variable (dwarf nova) [UGSS - SS Cyg type, UGSU - SU UMa type, UGZ - Z Cam type, UGWZ - WZ Sge type]
 
UV UV Cet type (flare star)
X X-ray binary [Xp - X-ray pulsar]
ZAnd Z And type cataclysmic binary (symbiotic variable)

The 'Max' and 'Min' magnitudes are all visual except where the 'Min' is followed by a 'p', in which case they are both photographic.

In the Eclipsing Binary Program list, the 'D' column gives the duration of the eclipse in hours. This is only well-defined for Algol type (EA) stars. 'EB' or 'EW' in this column indicates that the star is a Beta Lyrae or W UMa star.

The 'Chart' column gives the identifier or date of the latest version of the chart. A star name in this column indicates that the star is included on a combined chart under the name of another star. Where there is no date entered, the chart is currently being prepared.
