Type Ia SN 2012ij opt. & NIR spectra
In this paper, we present photometric and spectroscopic observations of the subluminous Type Ia supernova (SNIa) 2012ij, which has an absolute B-band peak magnitude... -
Herbig Ae/Be stars with IGRINS obs.
Accretion plays an important role in protoplanetary disk evolution, and it is thought that the accretion mechanism changes between low- and high-mass stars. Here we characterize... -
Cerium abundances in open clusters from OCCAM
The APOGEE Open Cluster Chemical Abundances and Mapping survey is used to probe the chemical evolution of the s-process element cerium in the Galactic disk. Cerium abundances... -
3-D kinematics of Orion Nebula Cluster
The kinematics and dynamics of stellar and substellar populations within young, still-forming clusters provide valuable information for constraining theories of formation... -
Nature of PAH in PG quasars from Spitzer/IRS sp.
We reanalyze the mid-infrared (5-40{mu}m) Spitzer spectra of 86 low-redshift (z<0.5) Palomar-Green quasars to investigate the nature of polycyclic aromatic hydrocarbon (PAH)... -
IRTF/iSHELL K-band sp. obs. of PMS stars
Magnetic fields and mass accretion processes create dark and bright spots on the surface of young stars. These spots manifest as surface thermal inhomogeneities, which alter the... -
596 Scheila NIR spectra before & after impact
Dust emission was detected on main-belt asteroid 596 Scheila in 2010 December and was attributed to the collision of a few-tens-of-meters projectile on the surface of the... -
Discovery of an L dwarf co-moving BD+60 1417
Through the Backyard Worlds: Planet 9 citizen science project we discovered a late-type L dwarf co-moving with the young K0 star BD+60 1417 at a projected separation of 37" or... -
NIR spectroscopic obs. of z>6.5 quasars
We report the results of near-infrared spectroscopic observations of 37 quasars in the redshift range 6.3<z<=7.64, including 32 quasars at z>6.5, forming the largest... -
GCLASS HST grism data of z~1 clusters
We present and publicly release (www.gclasshst.com) the first spatially resolved H{alpha} maps of star-forming cluster galaxies at z~1, made possible with the Wide Field Camera... -
CLEAR: HST G102 & G141 grism obs. of CANDELS gal.
We report on the gas-phase metallicity gradients of a sample of 238 star-forming galaxies at 0.6<z<2.6, measured through deep near-infrared Hubble Space Telescope slitless... -
V899 Mon opt-NIR spectra and light curves
The eruptive young star V899 Mon shows characteristics of both FUors and EXors. It reached a peak brightness in 2010, then briefly faded in 2011, followed by a second outburst.... -
Emission Line Galaxy Pairs from the WISP survey
We identify a sample of spectroscopically measured emission line galaxy (ELG) Pairs up to z=1.6 from the Wide Field Camera 3 (WFC3) Infrared Spectroscopic Parallels (WISP)... -
Limits on binary planets in HR 8799b, c & d
We place the first constraints on binary planets and exomoons from Doppler monitoring of directly imaged exoplanets. We model radial velocity observations of HR 8799 b, c, and d... -
NIR spectra of Nova V1674 Herculis
We present near-infrared spectroscopy of Nova Herculis 2021 (V1674 Her), obtained over the first 70 days of its evolution. This fastest nova on record displays a rich emission... -
Keck/NIRES spectrum of type Ia SN 2020qxp
We present and analyze a near-infrared (NIR) spectrum of the underluminous Type Ia supernova SN 2020qxp/ASASSN-20jq obtained with NIRES at the Keck Observatory, 191 days after... -
IGRINS YSO survey. I. PMS stars in Tau-Aur
We present fundamental parameters for 110 canonical K- and M-type (1.3-0.13M_{sun}_) Taurus-Auriga young stellar objects (YSOs). The analysis produces a simultaneous... -
NIR sp. of Class 0 protostars in Perseus and Orion
We present near-infrared K-band spectra for a sample of seven Class 0 protostars in the Perseus and Orion star-forming regions. We detect Br{gamma}, CO overtone, and H_2_... -
Ultracool Dwarfs with Spitzer IR Spectrograph. I.
We present Spitzer IRS 5-14{mu}m spectra and 16{mu}m and 22{mu}m photometry of the T2.5 companion to the ~300Myr old G0V star HN Peg. We incorporate previous 0.8-5{mu}m... -
VLT Spectroscopy of Ultra-faint Dwarf Galaxies
We perform consistent reductions and measurements for three ultra-faint dwarf galaxies (UFDs): Bootes I, Leo IV, and Leo V. Using the public archival data from the GIRAFFE...
