Looking for Distributed Star Formation in L1630: A Near-infrared (J, H, K) Survey [PDF]

, 1997
We have carried out a simultaneous, multi-band (J, H, K) survey over an area of 1320 arcmin^2 in the L1630 region, concentrating on the region away from the dense molecular cores and with modest visual extinctions (\leq 10 mag).

Stellar or Non-Stellar Light? Determining Near-Infrared Contamination in Low Mass X-ray Binaries [PDF]

, 2009
Low-mass X-ray binary (LMXB) systems are comprised of a low-mass, K or M dwarflike star orbiting a compact object. Stellar black hole masses and their distributions are important inputs for binary evolution and supernova models.

Unveiling the Structure of Pre-Transitional Disks

, 2010
In the past few years, several disks with inner holes that are empty of small dust grains have been detected and are known as transitional disks. Recently, Spitzer has identified a new class of "pre-transitional disks" with gaps; these objects have an ...

The dust-eliminated shape of quasar spectra in the near-infrared: a hidden part of the big blue bump [PDF]

, 2005
The near-infrared shape of the big blue bump component in quasar spectra has been essentially unknown. It usually cannot be observed directly, due to the strong hot dust emission which dominates quasar spectra longward of ~1micron.

Intraoperative detection of parathyroid glands by autofluorescence identification using image-based system: report of 15 cases

Journal of Medical Case Reports, 2021
Background A detection of parathyroid glands by the evaluation of their autofluorescence in the near-infrared spectrum is considered as a promising tool in addition to their visual verification.

No disks around low-mass stars and brown dwarfs in the young sigma Orionis cluster? [PDF]

, 2001
We report on the analysis of 2MASS near-infrared data of a sample of low-mass stars and brown dwarfs in the sigma Orionis cluster. Youth and cluster membership have been spectroscopically confirmed using the Li I spectral line. We find little evidence in

Near-Infrared Super Resolution Imaging with Metallic Nanoshell Particle Chain Array

, 2012
We propose a near-infrared super resolution imaging system without a lens or a mirror but with an array of metallic nanoshell particle chain. The imaging array can plasmonically transfer the near-field components of dipole sources in the incoherent and ...

IRTF Observations of White Dwarfs with Possible Near-Infrared Excess [PDF]

, 2009
Near-infrared photometry and spectroscopy is obtained for a heterogeneous sample of nearby white dwarfs with possible excess flux as identified primarily in the Two Micron All Sky Survey. Among the sample of 43 stars are a number of white dwarfs that are
