A frozen super-Earth orbiting a star at the bottom of the Main Sequence
D. Kubas, J. P. Beaulieu, D. P. Bennett +19
We observed the microlensing event MOA-2007-BLG-192 at high angular resolution in JHKs with the NACO adaptive optics system on the VLT while the object was still amplified by a fac…
Evolution of Spin Direction of Accreting Magnetic Protostars and Spin-Orbit Misalignment in Exoplanetary Systems: II. Warped Discs
Francois Foucart, Dong Lai
Magnetic interactions between a protostar and its accretion disc tend to induce warping in the disc and produce secular changes in the stellar spin direction, so that the spin axis…
Exo-Planetary Transits of Limb Brightened Lines; Tentative Si IV Absorption by HD209458b
Everett Schlawin, Eric Agol, Lucianne Walkowicz +2
Transit light curves for stellar continua have only one minimum and a "U" shape. By contrast, transit curves for optically thin chromospheric emission lines can have a "W" shape be…
Evolution of Spin Direction of Accreting Magnetic Protostars and Spin-Orbit Misalignment in Exoplanetary Systems
Dong Lai, Francois Foucart, Douglas N. C. Lin
Recent observations have shown that in many exoplanetary systems the spin axis of the parent star is misaligned with the planet's orbital axis. These have been used to argue agains…
Physical characteristics and non-keplerian orbital motion of "propeller" moons embedded in Saturn's rings
Matthew S. Tiscareno, Joseph A. Burns, Miodrag Sremčević +8
We report the discovery of several large "propeller" moons in the outer part of Saturn's A ring, objects large enough to be followed over the 5-year duration of the Cassini mission…
The shape and dynamics of a heliotropic dusty ringlet in the Cassini Division
M. M. Hedman, J. A. Burt, J. A. Burns +1
The so-called "Charming Ringlet" (R/2006 S3) is a low-optical-depth, dusty ringlet located in the Laplace gap in the Cassini Division. This ringlet is particularly interesting beca…
The Lyot Project Direct Imaging Survey of Substellar Companions: Statistical Analysis and Information from Nondetections
Jérémy leconte, Rémi Soummer, Sasha Hinkley +14
The Lyot project used an optimized Lyot coronagraph with Extreme Adaptive Optics at the 3.63m Advanced Electro-Optical System telescope (AEOS) to observe 86 stars from 2004 to 2007…
Mass Transfer, Transiting Stream and Magnetopause in Close-in Exoplanetary Systems with Applications to WASP-12
Dong Lai, Ch. Helling, E. P. J. van den Heuvel
We study mass transfer by Roche lobe overflow in close-in exoplanetary systems. The planet's atmospheric gas passes through the inner Lagrangian point and flows along a narrow stre…
Spitzer Secondary Eclipses of WASP-18b
Sarah Nymeyer, Joseph Harrington, Ryan A. Hardy +16
The transiting exoplanet WASP-18b was discovered in 2008 by the Wide Angle Search for Planets (WASP) project. The Spitzer Exoplanet Target of Opportunity Program observed secondary…
On the Orbit of Exoplanet WASP-12b
Christopher J. Campo, Joseph Harrington, Ryan A. Hardy +17
We observed two secondary eclipses of the exoplanet WASP-12b using the Infrared Array Camera on the Spitzer Space Telescope. The close proximity of WASP-12b to its G-type star resu…
