BAA VSS PROGRAMMES AND CHARTS
The Binocular Programme
This catalogue (V6.4 PDF, 38kb) lists all of the stars on the Section's Binocular Variable Star Programme . Charts for these stars can be ordered from the Chart 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.
