Massive stars in APOGEE2 Survey. III.
We have applied the semi-empirical spectral analysis, developed by the Sloan Digital Sky Survey (SDSS)-IV/Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE2)... -
Absorption lines in 21 Lyn A-type star
We present a catalog of absorption lines in the z', Y, and J bands that we identified in 21 Lyn, a slowly rotating A0.5V star. We detected 155 absorption features in the... -
MW Project: DR2 "yellow balls" in Spitzer
Yellowballs (YBs) were first discovered during the Milky Way Project (MWP) citizen science initiative. The MWP users noticed compact, yellow regions in Spitzer Space Telescope... -
APOGEE2-N NIR spectra of B-type stars
We present a semi-empirical spectral classification scheme for normal B-type stars using near-infrared (NIR) spectra (1.5-1.7{mu}m) from the Sloan Digital Sky Survey Apache... -
Massive stars in SDSS/APOGEE-2. II. W3-W4-W5
In this work, we have applied a semi-empirical spectral classification method for OB-stars using the APOGEE spectrograph to a sample of candidates in the W3-W4-W5 (W345)... -
Brown dwarf surface gravities with Keck/NIRSPEC
We combine 131 new medium-resolution (R~2000) J-band spectra of M, L, and T dwarfs from the Keck NIRSPEC Brown Dwarf Spectroscopic Survey (BDSS) with 97 previously published... -
Gaia-Kepler stellar properties catalog. II. Planets
Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using the Gaia... -
New AO obs. of exoplanets & brown dwarf companions
The orbital eccentricities of directly imaged exoplanets and brown dwarf companions provide clues about their formation and dynamical histories. We combine new high-contrast... -
NIR spectroscopy of Galactic Wolf-Rayet stars. II.
We are continuing a J, K and narrowband imaging survey of 300{deg}^2^ of the plane of the Galaxy, searching for new Wolf-Rayet (W-R) stars. Our survey spans 150{deg} in Galactic... -
T CrA polarization image
In recent years, a new hot-topic has emerged in the star and planet formation field, namely, the interaction between the circumstellar disk and its birth cloud. The birth... -
Near-IR spectra of inner red giants
The existence in the Milky Way of either a long thin bar with a half length of 4.5kpc and a position angle of around 45{deg} with respect to the Sun-Galactic centre line or a... -
Late-type stars in the inner Milky Way
We present the results of a narrow-band infrared imaging survey of a narrow strip (12' wide) around the Galactic equator between 6{deg} and 21{deg} of galactic longitude aimed... -
O, B and Be stars equivalent widths
We present an atlas of spectra of O- and B-type stars, obtained with the Short Wavelength Spectrometer (SWS) during the Post-Helium program of the Infrared Space Observatory... -
K & M giants equivalent widths
The analyses of high resolution infrared spectra have been done for CN lines in oxygen-rich cool evolved stars including 2 K giants, 20 M giants and 1 S-type star. Since CN... -
The VMC survey XLI - PMs within the SMC
We used data from the near-infrared Visible and Infrared Telescope for Astronomy (VISTA) survey of the Magellanic Cloud system (VMC) to measure proper motions (PMs) of stars... -
IR and sub-mm variability in protostars
We study the relationship between the mid-infrared (mid-IR) and sub-millimetre (sub-mm) variability of deeply embedded protostars using the multi-epoch data from the Wide-field... -
Period-luminosity relation of red supergiants
We revisit the K-band period-luminosity (P-L) relations of Galactic red supergiants using Gaia Data Release 2 parallaxes and up to 70yr of photometry from AAVSO and ASAS... -
Cool KOIs. VI. H- and K- band spectra
We present H- and K-band spectra for late-type Kepler Objects of Interest (the "Cool KOIs"): low-mass stars with transiting-planet candidates discovered by NASA's Kepler Mission... -
IR high-res. sp. of hot cores of AFGL2591 & AFGL2136
We have performed a high-resolution 4-13{mu}m spectral survey of the hot molecular gas associated with the massive protostars AFGL 2591 and AFGL 2136, utilizing the Echelon... -
ALMA observation of 152 1-11Myr aged stars
We utilize ALMA archival data to estimate the dust disk size of 152 protoplanetary disks in Lupus (1-3Myr), Chamaeleon I (2-3Myr), and Upper-Sco (5-11Myr). We combine our sample...
