Retired A Stars and Their Companions. III. Comparing the Mass-Period Distributions of Planets Around A-Type Stars and Sun-Like Stars

Brendan P. Bowler, John Asher Johnson, Geoffrey W. Marcy +8

We present an analysis of ~5 years of Lick Observatory radial velocity measurements targeting a uniform sample of 31 intermediate-mass subgiants (1.5 < M*/Msun < 2.0) with the goal…

Metallicity of the Massive Protoplanets Around HR 8799 If Formed by Gravitational Instability

R. Helled, P. Bodenheimer

The final composition of giant planets formed as a result of gravitational instability in the disk gas depends on their ability to capture solid material (planetesimals) during the…

Refining Exoplanet Ephemerides and Transit Observing Strategies

Stephen R. Kane, Suvrath Mahadevan, Kaspar von Braun +2

Transiting planet discoveries have yielded a plethora of information regarding the internal structure and atmospheres of extra-solar planets. These discoveries have been restricted…

Discovery and Characterization of Transiting SuperEarths Using an All-Sky Transit Survey and Follow-up by the James Webb Space Telescope

D. Deming, S. Seager, J. Winn +9

Doppler and transit surveys are finding extrasolar planets of ever smaller mass and radius, and are now sampling the domain of superEarths (1-3 Earth radii). Recent results from th…
