Ground-based Spectroscopy of the Exoplanet XO-2b using a Systematic Wavelength Calibration

Kyle A. Pearson, Caitlin A. Griffith, Robert T. Zellem +2

Exoplanets orbiting close to their host star are expected to support a large ionosphere, which extends to larger pressures than witnessed in our Solar System. These ionospheres can…

XO-2b: a hot Jupiter with a variable host star that potentially affects its measured transit depth

Robert T. Zellem, Caitlin A. Griffith, Kyle A. Pearson +6

The transiting hot Jupiter XO-2b is an ideal target for multi-object photometry and spectroscopy as it has a relatively bright (-mag = 11.25) K0V host star (XO-2N) and a large p…
