MagAO Imaging of Long-period Objects (MILO). I. A Benchmark M Dwarf Companion Exciting a Massive Planet around the Sun-like Star HD 7449
Timothy J. Rodigas, Pamela Arriagada, Jackie Faherty +17
We present high-contrast Magellan adaptive optics (MagAO) images of HD 7449, a Sun-like star with one planet and a long-term radial velocity (RV) trend. We unambiguously detect the…
The LEECH Exoplanet Imaging Survey: Characterization of the Coldest Directly Imaged Exoplanet, GJ 504 b, and Evidence for Super-Stellar Metallicity
Andrew J. Skemer, Caroline V. Morley, Neil T. Zimmerman +39
As gas giant planets and brown dwarfs radiate away the residual heat from their formation, they cool through a spectral type transition from L to T, which encompasses the dissipati…
Accreting Protoplanets in the LkCa 15 Transition Disk
S. Sallum, K. B. Follette, J. A. Eisner +14
Exoplanet detections have revolutionized astronomy, offering new insights into solar system architecture and planet demographics. While nearly 1900 exoplanets have now been discove…
Magellan Adaptive Optics first-light observations of the exoplanet beta Pic b. II. 3-5 micron direct imaging with MagAO+Clio, and the empirical bolometric luminosity of a self-luminous giant planet
Katie M. Morzinski, Jared R. Males, Andy J. Skemer +14
Young giant exoplanets are a unique laboratory for understanding cool, low-gravity atmospheres. A quintessential example is the massive extrasolar planet Pic b, which is 9 AU f…
The LEECH Exoplanet Imaging Survey: Orbit and Component Masses of the Intermediate Age, Late-Type Binary NO UMa
Joshua E. Schlieder, Andrew J. Skemer, Anne-Lise Maire +21
We present high-resolution Large Binocular Telescope LBTI/LMIRcam images of the spectroscopic and astrometric binary NO UMa obtained as part of the LBTI Exozodi Exoplanet Common Hu…
Direct imaging of an asymmetric debris disk in the HD 106906 planetary system
Paul G. Kalas, Abhijith Rajan, Jason J. Wang +53
We present the first scattered light detections of the HD 106906 debris disk using Gemini/GPI in the infrared and HST/ACS in the optical. HD 106906 is a 13 Myr old F5V star in the…
Astrometric Confirmation and Preliminary Orbital Parameters of the Young Exoplanet 51 Eridani b with the Gemini Planet Imager
Robert J. De Rosa, Eric L. Nielsen, Sarah C. Blunt +47
We present new Gemini Planet Imager observations of the young exoplanet 51 Eridani b which provide further evidence that the companion is physically associated with 51 Eridani. Com…
Direct Exoplanet Detection with Binary Differential Imaging
Timothy J. Rodigas, Alycia Weinberger, Eric E. Mamajek +5
Binaries are typically excluded from direct imaging exoplanet surveys. However, the recent findings of Kepler and radial velocity programs show that planets can and do form in bina…
Pictoris' inner disk in polarized light and new orbital parameters for Pictoris b
Maxwell A. Millar-Blanchaer, James R. Graham, Laurent Pueyo +54
We present -band observations of Pic with the Gemini Planet Imager's (GPI's) polarimetry mode that reveal the debris disk between ~0.3" (~6 AU) and ~1.7" (~33 AU), while sim…
Gemini Planet Imager Observations of the AU Microscopii Debris Disk: Asymmetries within One Arcsecond
Jason J. Wang, James R. Graham, Laurent Pueyo +42
We present Gemini Planet Imager (GPI) observations of AU Microscopii, a young M dwarf with an edge-on, dusty debris disk. Integral field spectroscopy and broadband imaging polarime…
New Extinction and Mass Estimates of the Low-mass Companion 1RXS 1609 B with the Magellan AO System: Evidence of an Inclined Dust Disk
Ya-Lin Wu, Laird M. Close, Jared R. Males +9
We used the Magellan adaptive optics system to image the 11 Myr substellar companion 1RXS 1609 B at the bluest wavelengths to date (z' and Ys). Comparison with synthetic spectra yi…
Multiwavelength Observations of NaSt1 (WR 122): Equatorial Mass Loss and X-rays from an Interacting Wolf-Rayet Binary
Jon C. Mauerhan, Nathan Smith, Schuyler D. Van Dyk +5
NaSt1 (aka Wolf-Rayet 122) is a peculiar emission-line star embedded in an extended nebula of [N II] emission with a compact dusty core. This object was characterized by Crowther &…
First-light LBT nulling interferometric observations: warm exozodiacal dust resolved within a few AU of eta Corvi
D. Defrère, P. M. Hinz, A. J. Skemer +37
We report on the first nulling interferometric observations with the Large Binocular Telescope Interferometer (LBTI), resolving the N' band (9.81 - 12.41 um) emission around the ne…
New Spatially Resolved Observations of the T Cha Transition Disk and Constraints on the Previously Claimed Substellar Companion
S. Sallum, J. A. Eisner, Laird M. Close +11
We present multi-epoch non-redundant masking observations of the T Cha transition disk, taken at the VLT and Magellan in H, Ks, and L' bands. T Cha is one of a small number of tran…
