Even more evidence that stellar mass is an important factor in the properties of the planetary system.

I see so many giant stars at great distances do host extrasolar jovian planets. I wonder if also nearby ones do.

Pollux does and so does Gamma Cephei.

Aldebaran and Arcturus seem having still unconfirmed companions....

I had got an old paper with some G-K giants with peculiar periodicities. Nearly those same periods were still reported in a recent paper Lazarus posted in "Unconfirmed planets" thread and I still wonder if they may turn out being orbital periods of low mass or substellar companions. Amongst the stars mentioned and with significant periodicities:

- Aldebaran - suspected having a superjovian planet
- Arcturus - ditto
- Pollux - confirmed planet
- Iota Aurigae - a couple of brown dwarfs?
- 15 Librae (or Ksi2 Librae)
- Beta Ceti

Who knows, maye Okayama Planet Search could unveil the presence or not of planetary companions out there. rabbit
