[vsnet-chat 5496] RE: [AAVSO-DIS] GDOR stars

["Eric Broens" <Eric.Broens@skynet.be>]

Hello Noel,

At first I also thought it would be gamma Dor stars. However gamma Dor
itself is an eclipsing binary classified as EW: in the GCVS. I was confused
since there was no explanation in the documentation of the GCVS.

I found the explanation in Namelist 75 (IBVS 4870).
Following explanation is given:

"GDOR - gamma Doradus stars.  Early type F dwarfs showing (multiple)
periods from several tenths of a day to slightly in excess of one day.
Amplitudes usually do not exceed 0.1 mag.  Presumably low degree g-mode
non-radial pulsators. Prototype: gamma Dor."

In the GCVS, including Namelists 67-76, following GDOR stars can be found:
