New Worlds: Evaluating terrestrial planets as astrophysical objects
Caleb A. Scharf, David S. Spiegel, Mark Chandler +4
Terrestrial exoplanets are on the verge of joining the ranks of astronomically accessible objects. Interpreting their observable characteristics, and informing decisions on instrum…
Can TiO Explain Thermal Inversions in the Upper Atmospheres of Irradiated Giant Planets?
David S. Spiegel, Katie Silverio, Adam Burrows
Spitzer Space Telescope infrared observations indicate that several transiting extrasolar giant planets have thermal inversions in their upper atmospheres. Above a relative minimum…
A possible dearth of hot gas in galaxy groups at intermediate redshift
David S. Spiegel, Frits Paerels, Caleb A. Scharf
We examine the X-ray luminosity of galaxy groups in the CNOC2 survey, at redshifts 0.1 < z < 0.6. Previous work examining the gravitational lensing signal of the CNOC2 groups has s…
