NIKA2 observations around LBV stars Emission from stars and circumstellar material [PDF]

open access: yesEPJ Web of Conferences, 2020
Luminous Blue Variable (LBV) stars are evolved massive objects, previous to core-collapse supernova. LBVs are characterized by photometric and spectroscopic variability, produced by strong and dense winds, mass-loss events and very intense UV radiation ...

The radio-infrared correlation in galaxies [PDF]

open access: yes, 2009
The radio-infrared correlation was explained as a direct and linear relationship between star formation and IR emission. However, one fact making the IR-star formation linkage less obvious is that the IR emission consists of at least two emission ...

ALMA Observation of NGC 5135: The Circumnuclear CO (6–5) and Dust Continuum Emission at 45 pc Resolution* [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract We present high-resolution (0.″17 × 0.″14) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the CO (6–5) line and 435 μm dust continuum emission within a ∼9″ × 9″ area centered on the nucleus of the galaxy NGC 5135.

ALMA uncovers the [C ii] emission and warm dust continuum in a z = 8.31 Lyman break galaxy [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We report on the detection of the [C ii] 157.7 μm emission from the Lyman break galaxy (LBG) MACS0416_Y1 at z = 8.3113, by using the Atacama Large Millimeter/submillimeter Array (ALMA). The luminosity ratio of [O iii] 88 μm (from previous campaigns) to [C ii] is 9.3 ± 2.6, indicative of hard interstellar radiation fields and/or ...

ALMA Observations of Circumstellar Disks in the Upper Scorpius OB Association [PDF]

open access: yes, 2016
We present ALMA observations of 106 G-, K-, and M-type stars in the Upper Scorpius OB Association hosting circumstellar disks. With these data, we measure the 0.88 mm continuum and $^{12}$CO $J$ = 3$-$2 line fluxes of disks around low-mass ($0.14-1.66 ...

Identifying circumstellar dust around oxygen-rich mira variables with maser emission via continuum elimination [PDF]

open access: yes, 2021
Stars between about 0.8 and 8 times the mass of the Sun will eventually evolve, becoming asymptotic giant branch (AGB) stars, where they pulsate and eject mass from their atmospheres, forming dust shells in the space around them. Evolved low- and intermediate-mass stars with carbon-to-oxygen ratios (C/O) below unity are known as oxygen-rich stars.

Imaging of 2-mm dust continuum emission towards S106 FIR and its spectral energy distribution [PDF]

open access: yesSymposium - International Astronomical Union, 2002
The class 0 source S106 FIR is a good candidate to investigate a very early phase of star formation because of the presence of an AU-scale Microjet, discovered by our VLBA H2O maser observations and the absence of an extensive CO outflow. In order to reveal the properties of S106 FIR, we conducted observations of 2-mm continuum emission with the ...

Detection of CO and Dust Emission in Near-Infrared Spectra of SN 1998S [PDF]

open access: yes, 1999
Near-infrared spectra (0.95 -- 2.4 micron) of the peculiar Type IIn supernova 1998S in NGC 3877 from 95 to 355 days after maximum light are presented. K-band data taken at days 95 and 225 show the presence of the first overtone of CO emission near 2.3 ...

Bolocam Survey for 1.1 mm Dust Continuum Emission in the c2d Legacy Clouds. I. Perseus [PDF]

open access: yesThe Astrophysical Journal, 2006
We have completed a 1.1 mm continuum survey of 7.5 sq deg of the Perseus Molecular Cloud using Bolocam at the Caltech Submillimeter Observatory. This represents the largest millimeter or submillimeter continuum map of Perseus to date. Our map covers more than 30,000 31" (FWHM) resolution elements to a 1 sigma RMS of 15 mJy/beam.
