Which Radial Velocity Exoplanets Have Undetected Outer Companions? (2009)
Rodigas, Timothy J., Hinz, Philip M.
(Abridged) The observed radial velocity (RV) eccentricity distribution for extrasolar planets in single-planet systems shows that a significant fraction of planets are eccentric ($e > 0.1$). Here we...
Hinz, Philip M., Kenyon, Scott, Meyer, Michael R., Boss, Alan, Angel, Roger
The detection of lower mass planets now being reported via radial velocity and microlensing surveys suggests that they may be ubiquitous. If missions such as Kepler are able to confirm this, the...

A candidate < 3 Jupiter mass, extrasolar planet was recently imaged by Kalas et al. (2008) using HST/ACS at 12.7" (96 AU) separation from the nearby (d = 7.7 pc) young (~200 Myr) A2V star Fomalhaut....
Deep L' and M-band Imaging for Planets Around Vega and epsilon Eridani (2008)
Heinze, A. N., Hinz, Philip M., Kenworthy, Matthew, Miller, Douglas, Sivanandam, Suresh
We have obtained deep Adaptive Optics (AO) images of Vega and epsilon Eri to search for planetary-mass companions. We observed at the MMT in the L' (3.8 micron) and M (4.8 micron) bands using Clio, a...
Imaging Circumstellar Environments with a Nulling Interferometer (2007)
Philip M. Hinz, William F. Hoffmann, J. Roger, P. Angel, ...
on, allowing direct detection of warm, Jupiter-size planets and faint zodiacal dust around other nearby stars 5 . With a conventional telescope, the very high contrast ratio needed to resolve a...
First On-Sky High Contrast Imaging with an Apodizing Phase Plate (2007)
Kenworthy, Matthew A., Codona, Johanan L., Hinz, Philip M., Angel, J. Roger P., Heinze, Ari, Sivanandam, Suresh
We present the first astronomical observations obtained with an Apodizing Phase Plate (APP). The plate is designed to suppress the stellar diffraction pattern by 5 magnitudes from 2-9 lambda/D over a...
Hinz, Philip M., Heinze, A. N., Sivanandam, Suresh, Miller, Douglas L., Kenworthy, Matthew A., Brusa, Guido, ...
Vega may have a massive companion in a wide orbit, as evidenced by structure in its cold dust debris. We have tested this hypothesis by direct imaging with adaptive optics in the M band. The...
SDSSJ102111.02+491330.4: A Newly Discovered Gravitationally Lensed Quasar (2005)
Pindor, Bart, Eisenstein, Daniel J., Gregg, Michael D., Becker, Robert H., Inada, Naohisa, Oguri, Masamune, ...
We report follow-up observations of two gravitational lens candidates identified in the Sloan Digital Sky Survey (SDSS) dataset. We have confirmed that SDSS J102111.02+491330.4 is a previously...
Mamajek, Eric E., Meyer, Michael R., Hinz, Philip M., Hoffmann, William F., Cohen, Martin, Hora, Joseph L.
We have conducted an N-band survey of 14 young stars in the ~30 Myr-old Tucana-Horologium Association to search for evidence of warm, circumstellar dust disks. Using the MIRAC-BLINC camera on the...
Klio: A 5 micron camera for the detection of giant exoplanets (2003)
Freed, Melanie, Hinz, Philip M., Meyer, Michael R.
We plan to take advantage of the unprecedented combination of low thermal background and high resolution provided by the 6.5m MMT's adaptive secondary mirror, to target the 3-5 micron atmospheric...
Hinz, Philip M., Hoffmann, William F., Hora, Joseph L.
Physical models of circumstellar disks surrounding pre-main sequence stars are currently constrained primarily by the spectral energy distribution (SED) of the system. Here we present first results...
