MagAO Imaging of Long-period Objects (MILO). II. A Puzzling White Dwarf around the Sun-like Star HD 11112
Timothy J. Rodigas, P. Bergeron, Amelie Simon +18
HD 11112 is an old, Sun-like star that has a long-term radial velocity (RV) trend indicative of a massive companion on a wide orbit. Here we present direct images of the source res…
L-band Spectroscopy with Magellan-AO/Clio2: First Results on Young Low-Mass Companions
Jordan M. Stone, Josh Eisner, Andy Skemer +6
L-band spectroscopy is a powerful probe of cool low-gravity atmospheres: The P, Q, and R branch fundamental transitions of methane near 3.3 m provide a sensitive probe of carbon…
New Extinction and Mass Estimates from Optical Photometry of the Very Low Mass Brown Dwarf Companion CT Chamaeleontis B with the Magellan AO System
Ya-Lin Wu, Laird M. Close, Jared R. Males +9
We used the Magellan adaptive optics (MagAO) system and its VisAO CCD camera to image the young low mass brown dwarf companion CT Chamaeleontis B for the first time at visible wave…
On the Morphology and Chemical Composition of the HR 4796A Debris Disk
Timothy J. Rodigas, Christopher C. Stark, Alycia Weinberger +17
[abridged] We present resolved images of the HR 4796A debris disk using the Magellan adaptive optics system paired with Clio-2 and VisAO. We detect the disk at 0.77 \microns, 0.91…
An Enigmatic Pointlike Feature within the HD 169142 Transitional Disk
Beth A. Biller, Jared Males, Timothy Rodigas +13
We report the detection of a faint pointlike feature possibly related to ongoing planet-formation in the disk of the transition disk star HD 169142. The pointlike feature has a …
Polarized Light Imaging of the HD 142527 Transition Disk with the Gemini Planet Imager: Dust around the Close-in Companion
Timothy J. Rodigas, Katherine B. Follette, Alycia Weinberger +2
When giant planets form, they grow by accreting gas and dust. HD 142527 is a young star that offers a scaled-up view of this process. It has a broad, asymmetric ring of gas and dus…
