The ISM local to the runaway star WR16
(Oxford University Press, 2020)
Massive stars leave their imprint on the interstellar medium as they radiate their energy and undergo episodes of mass ejection throughout their lives. In this paper, we analyse the case of the Wolf-Rayet star WR16 combining ...
Cool stars in the Galactic center as seen by APOGEE: M giants, AGB stars, and supergiant stars and candidates
(EDP Sciences, 2020)
The Galactic center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and stellar crowding. Large, near-IR spectroscopic surveys, such as ...
Stellar and planetary characterization of the ross 128 exoplanetary system from APOGEE spectra
(IOP Publishing, 2018-06-10)
The first detailed chemical abundance analysis of the M-dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5-1.7 mu m), high-resolution (R similar to 22,500) spectra from the SDSS ...
Chemical abundances of main-sequence, turnoff, subgiant, and red giant stars from APOGEE Spectra. I. Signatures of diffusion in the open cluster M67
(IOP Publishing Ltd, 2018)
Detailed chemical abundance distributions for 14 elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of similar to 4 Gyr. The eight stars consist of ...
Deep transfer learning for star cluster classification: I. application to the PHANGS–HST survey
(Oxford University Press, 2020)
We present the results of a proof-of-concept experiment that demonstrates that deep learning can successfully be used for production-scale classification of compact star clusters detected in Hubble Space Telescope (HST) ...
Millimagnitude optical photometry for the transiting planetary candidate OGLE-TR-109
(UNIV CHICAGO PRESS, 2006-08-10)
We present precise V-band photometry for the low-amplitude transit candidate star OGLE-TR-109. This is an extreme case among the transiting candidates found by the OGLE group because of the early spectral type of the star ...
Assessing Molecular Outflows and Turbulence in the Protostellar Cluster Serpens South
(The American Astronomical Society., 2015-04-10)
Molecular outflows driven by protostellar cluster members likely impact their surroundings and contribute to
turbulence, affecting subsequent star formation. The very young Serpens South cluster consists of a particularly
high ...
G345.45+1.50: an expanding ring-like structure with massive star formation
(EDP Sciences, 2016)
Context. Ring-like structures in the interstellar medium (ISM) are commonly associated with high-mass stars. Kinematic studies of large structures in giant molecular clouds (GMCs) toward these ring-like structures may help ...
Studying star-forming processes at core and clump scales: the case of the young stellar object G29.862-0.0044
(EDP Science, 2020)
Aims. To advance our knowledge of star formation, in addition to statistical studies and large surveys of young stellar objects (YSOs), it is important to carry out detailed studies towards particular objects. Given that ...
IRAS 16547−4247: A New Candidate of a Protocluster Unveiled with ALMA
(American Astronomical Society, 2015)
We present the results of continuum and 12CO(3–2) and CH3OH(7–6) line observations of IRAS 16547−4247
made with the Atacama Large Millimeter/submillimeter Array (ALMA) at an angular resolution of ∼0.
5. The
12CO(3–2) ...
