FCAPT uvby Photometry of the mCP Stars HD 16545, HD 93226, HR 7575, and HR 8206

Adelman, Saul J.

The Four College Automated Photoelectric Telescope (FCAPT) obtained differential Strömgren uvby observations of the magnetic CP (mCP) stars HD 16545, HD 93226, HR 7575, and HR 8206. These are the first reported from the FCAPT. HD 16545, with its largest amplitudes (0.06 mag) being those in v and in b, has a period of 1.61926 days, close to its per…

Revised Periods for QS Geminorum and V367 Geminorum

Brown, Peter J.; Hintz, Eric G.

We have examined the field around the variable stars QS Geminorum and V367 Geminorum. For the δ Scuti-type variable QS Gem, we determined a revised period of 0.1346116 days, which is close to the originally published period from Hipparcos. For the eclipsing system V367 Gem, we found a period of 0.6992285 days, which is substantially different from…
