Title: Doppler Tomographic Observations of the Longest Period A Star Transiting Planet

Abstract: Only a handful of planets are known transiting A-type main sequence stars (Teff > 7000 K), as these stars are rapidly rotating and have typically been ignored by transit surveys. Nonetheless, the planetary population of these stars is important for constraining models of planet formation and migration. We propose to observe a transit of our newly-validated A star transiting planet 2MASS J06101557+2436535 b, using Doppler tomographic methodology with GRACES. This will allow us to not only fully confirm this as a genunine planet, but also measure the alignment (or lack thereof) between the stellar spin axis and planetary orbital plane, which is important for constraining planetary migration models.
