Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
We report the direct imaging discovery of a third exoplanet in the Pictoris system. We detect Pictoris d ( Pic d) in non-coronagraphic observations obtained with VLT/ERI…
High-contrast spectroscopy with the new VLT/ERIS instrument: Molecular maps and radial velocity of the gas giant AF Lep b
Jean Hayoz, Markus Johannes Bonse, Felix Dannert +66
The Enhanced Resolution Imager and Spectrograph (ERIS) is the new Adaptive-Optics (AO) assisted Infrared instrument at the Very Large Telescope (VLT). Its refurbished Integral Fiel…
Magellan AO System , , and Observations of the Very Wide 650 AU HD 106906 Planetary System
Ya-Lin Wu, Laird M. Close, Vanessa P. Bailey +8
We analyze archival data from Bailey and co-workers from the adaptive optics system and present the first 0.9 m detection ( mag; mag…
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…
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…
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…
Magellan Adaptive Optics first-light observations of the exoplanet Pic b. I. Direct imaging in the far-red optical with MagAO+VisAO and in the near-IR with NICI
Jared R. Males, Laird M. Close, Katie M. Morzinski +20
We present the first ground-based CCD (m) image of an extrasolar planet. Using MagAO's VisAO camera we detected the extrasolar giant planet (EGP) Pictoris b in -short…
Discovery of H-alpha Emission from the Close Companion Inside the Gap of Transitional Disk HD142527
L. M. Close, K. B. Follette, J. R. Males +10
We utilized the new high-order 585 actuator Magellan Adaptive Optics system (MagAO) to obtain very high-resolution visible light images of HD142527 with MagAO's VisAO science camer…
HD 106906 b: A planetary-mass companion outside a massive debris disk
Vanessa Bailey, Tiffany Meshkat, Megan Reiter +14
We report the discovery of a planetary-mass companion, HD 106906 b, with the new Magellan Adaptive Optics (MagAO) + Clio2 system. The companion is detected with Clio2 in three band…
Directly Imaged L-T Transition Exoplanets in the Mid-Infrared
Andrew J. Skemer, Mark S. Marley, Philip M. Hinz +15
Gas-giant planets emit a large fraction of their light in the mid-infrared (3m), where photometry and spectroscopy are critical to our understanding of the bulk propert…
The First Circumstellar Disk Imaged in Silhouette with Adaptive Optics: MagAO Imaging of Orion 218-354
Katherine B. Follette, Laird M. Close, Jared R. Males +11
We present high resolution adaptive optics (AO) corrected images of the silhouette disk Orion 218-354 taken with Magellan AO (MagAO) and its visible light camera, VisAO, in simulta…
First Light LBT AO Images of HR 8799 bcde at 1.65 and 3.3 Microns: New Discrepancies between Young Planets and Old Brown Dwarfs
Andrew J. Skemer, Philip M. Hinz, Simone Esposito +45
As the only directly imaged multiple planet system, HR 8799 provides a unique opportunity to study the physical properties of several planets in parallel. In this paper, we image a…
LBT observations of the HR 8799 planetary system: First detection of HR8799e in H band
S. Esposito, D. Mesa, A. Skemer +33
We have performed H and Ks band observations of the planetary system around HR 8799 using the new AO system at the Large Binocular Telescope and the PISCES Camera. The excellent in…
