Redder than Red: Discovery of an Exceptionally Red L/T Transition Dwarf

The Astrophysical Journal Letters, 2023
We present the discovery of CWISE J050626.96+073842.4 (CWISE J0506+0738), an L/T transition dwarf with extremely red near-infrared colors discovered through the Backyard Worlds: Planet 9 citizen science project. Photometry from UKIRT and CatWISE give a (

Infrared Variability of Evolved Protoplanetary Disks: Evidence for Scale Height Variations in the Inner Disk

, 2012
We present the results of a multi-wavelength multi-epoch survey of five evolved protoplanetary disks in the IC 348 cluster that show significant infrared variability.

Uncloaking globular clusters in the inner Galaxy [PDF]

, 2011
Extensive photometric studies of the globular clusters located towards the center of the Milky Way have been historically neglected. The presence of patchy differential reddening in front of these clusters has proven to be a significant obstacle to their

An Optical Survey of the Partially Embedded Young Cluster in NGC 7129 [PDF]

, 2015
NGC 7129 is a bright reflection nebula located in the molecular cloud complex near l=105.4, b=+9.9, about 1.15 kpc distant. Embedded within the reflection nebula is a young cluster dominated by a compact grouping of four early-type stars: BD+65 1638 (B3V)

The InfraRed Imaging Spectrograph (IRIS) for TMT: photometric precision and ghost analysis [PDF]

, 2018
The InfraRed Imaging Spectrograph (IRIS) is a first-light instrument for the Thirty Meter Telescope (TMT) that will be used to sample the corrected adaptive optics field by NFIRAOS with a near-infrared (0.8 - 2.4 $\mu$m) imaging camera and Integral Field

Near-Infrared Photometry of Metal Rich Globular Cluster M71 [PDF]

Journal of Astronomy and Space Sciences, 1997
We have carried out JK near-infrared photometry for the central region of the metal rich globular cluster M71, whose(K, J - K) color-magnitude diagram is presented here. Using two independent methods we derive the distance modulus to M71, 12.89 and 12.86
