NASA selects Penn State to lead next-generation planet finder
NASA Penn State lead next-generation planet finder
2016/4/13
A Penn State-led research group has been selected by NASA's Astrophysics Division to build a $10-million, cutting-edge instrument to detect planets orbiting stars outside our solar system. The team, l...
A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best matched by an averag...
A sub-Saturn Mass Planet, MOA-2009-BLG-319Lb
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/28
We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K or M-dwarf star in the inner Galactic disk or Galactic bulge. The high cadence observat...
WASP-33: The first delta Scuti exoplanet host star and evidence of star-planet interactions
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We report the discovery of photometric oscillations in the host star of the exoplanet WASP-33 b (HD 15082). The data were obtained in the R band both in transit and out-of-transit phases from the Mont...
HAT-P-26b: A Low-Density Neptune-Mass Planet Transiting a K Star
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/24
We report the discovery of HAT-P-26b, a transiting extrasolar planet orbiting the moderately bright V=11.744 K1 dwarf star GSC 0320-01027, with a period P = 4.234516 +- 0.000015 d, transit epoch Tc = ...
