RVel and BV photometry of 9 {gamma} Doradus stars
Listed in IVOA Registry (Virtual Observatory)
We have used precise photometric and high-dispersion spectroscopic observations to study nine candidate {gamma} Doradus ({gamma}Dor) stars, identified as optically variable comparison stars in our photometric studies of Sun-like stars.
Description
In this paper, we confirm these nine candidates as new {gamma}Dor variables. All exhibit sinusoidal variability with amplitudes between 6 and 65mmag in Johnson B and periods from 0.28 to 1.13days.
All lie in the same region of the H-R diagram as our previously confirmed {gamma}Dor stars. Of the nine systems, one is a single-lined spectroscopic binary (SB1), two are double-lined spectroscopic binaries (SB2), and the remaining six are single stars. We present orbits for the three binary systems: HD34415, HD144839, and HD182735.

Their periods are 6400days or 17.5yr (adopted), 995{+/-}7days, and 1052.4{+/-}0.2days, respectively. We compare our photometric periods with those we derive for six of the nine stars observed with the Transiting Exoplanet Survey Satellite to strengthen the confirmation of these new {gamma}Dor variables. Finally, because the distribution of {gamma}Dor stars in the H-R diagram overlaps with the red edge of the {delta} Scuti ({delta}Sct) instability strip, we use our ground-based photometric results for the 73 {gamma}Dor stars confirmed with our Automatic Photoelectric Telescopes over the past two decades to look at the incidence of hybrid {delta}Sct/{gamma}Dor stars; these are highly valuable targets for asteroseismology.
