Subject: Cataclysmic Variables from the Palomar-Green survey
Dear Mr. Kato:
The FSPACE CV Circular 1993.4 (FSPACE NO.5), edited by N.Makiguchi, says that
Japanese observers watch these cataclysmic variable stars:
SY Cnc (UGZ)
DO Dra (UGSS)
AH Her (UGZ)
T Leo (UGSU)
BZ UMa (UG)
CH UMa (UGSS)
SS UMi (UGSU)
PG0943+521 (CV)
The last, PG0943+521, especially interests me. The name of this cataclysmic
variable (CV) begins with "PG". This means it was found by the Palomar-Green
survey (Green, R. F., Schmidt, M., & Liebert, J. 1986, the Astrophysical Journal
Supplement, volume 61, page 305). My recent Ph.D. thesis was on these same
stars, the CVs found by the Palomar-Green survey. I call them "the PG CVs".
Since they were selected by color, and not by any outburst properties, they form
a statistically complete sample of CVs, which is useful for studying their
physical properties and evolution.
What I would like to know is, do you know anyone who observes any of the other
PG CVs? The Palomar-Green survey rediscovered many CVs that were already known,
including all the stars on the above list, other than PG0943+521. PG0943+521
was discovered for the first time by the Palomar-Green survey, as were several
other other CVs. Even with many of the stars that were already known, though
they have not been observed often, by professional or by amateur astronomers.
These include especially:
PG0834+488 = EI UMa
PG0859+415
PG0917+342
PG0943+521
PG1000+667
PG1341-079 = HS Vir
PG1510+234
PG1524+622
PG1633+115
PG1711+336 = V795 Her
PG1717+413 = V825 Her
PG2133+115, and
PG2337+123 = HX Peg.
Little is know of any of these stars' outburst properties, because so few
observations of them exist. All these stars could use more observations,
however, and I am very pleased that people observe them, and that you collect
the data.
Below are lists of them all, with both 1950 and 2000 coordinates. I have also
included lists of stars classified by Green as CVs, but which I find are really
not CVs. I call these the "NON-CVs". There are also stars in the survey that are
not in the complete sample, which I have not included here. Please keep up the
good work!

Notes:
(Column 7) Comment and Class, with designations of Green, Schmidt, & Liebert
(1986), but reclassified by me, and with new comments:
NO HA = sdB with H alpha weak or "missing" (Downes, R. A. 1987, ApJ,
316, 763)
VAR HA = variable H alpha line profile
