C17O and C18O spectra of nine AGB stars
We seek to investigate the ^17^O/^18^O ratio for a sample of AGB stars containing M-, S-, and C-type stars. These ratios are evaluated in relation to fundamental stellar... -
C/2012 F6 (Lemmon) and C/2013 R1 spectra (Lovejoy)
The apparition of bright comets C/2012 F6 (Lemmon) and C/2014 Q2 (Lovejoy) in March-April 2013 and January 2015, combined with the improved observational capabilities of... -
N2H+, N2D+ and C17O spectra in Ophiuchus
In cold (T<25K) and dense (n_H_>10^4^cm^-3^) interstellar clouds, molecules such as CO are significantly frozen onto dust grain surfaces. Deuterium fractionation is known... -
Mono-^13^C acetaldehydes mm/submm wave spectra
The acetaldehyde molecule is ubiquitous in the interstellar medium of our galaxy, and due to its dense and complex spectrum, large dipole moment, and several low-lying torsional... -
THz spectrum of the monodeuterated methyl formate
Laboratory spectral recordings and accurate molecular spectral analysis of any potential interstellar molecule are essential to generate a complete spectroscopic line list. This... -
C/2012 F6 (Lemmon) and C/2013 R1 (Lovejoy) spectra
A spectral survey in the 1mm wavelength range was undertaken in the long-period comets C/2012 F6 (Lemmon) and C/2013 R1 (Lovejoy) using the 30m telescope of the Institut de... -
Sub-mm images of SSTB213 J041757.75+274105.5
We observed the proto brown dwarf candidate SSTB213 J041757 with the Submillimeter Array to search for CO molecular outflow emission from the source. Our CO maps do not show any... -
Mm-spectra of comets C/2001 Q2 and C/2002 T7
The chemical composition of comets can be inferred using spectroscopic observations in submillimeter and radio wavelengths. We aim to compare the production rates ratio of... -
ALMA observations of 12CO/13CO around R Scl
The detached-shell source R Scl, displaying CO emission from recent mass loss, in a binary-induced spiral structure as well as in a clumpy shell produced during a thermal pulse,... -
Transitions in OMC-2 FIR 4 in the far-IR
Broadband spectral surveys of protostars offer a rich view of the physical, chemical and dynamical structure and evolution of star-forming regions. The Herschel Space... -
Millimetric and far-IR maps of IRDC 18310-4
Because of their short evolutionary time-scales, the earliest stages of high-mass star formation prior to the existence of any embedded heating source have barely been... -
MSX high-contrast IRDCs with NH_3_
Despite increasing research in massive star formation, little is known about its earliest stages. Infrared Dark Clouds (IRDCs) are cold, dense and massive enough to harbour the... -
A 3mm molecular line survey of NGC1068
We study the molecular composition of the interstellar medium (ISM) surrounding an active galactic nucleus (AGN), by making an inventory of molecular species and their... -
ATLASGAL cold high-mass clumps with NH_3_
The APEX Telescope Large Area Survey: The Galaxy (ATLASGAL) is an unbiased continuum survey of the inner Galactic disk at 870 micron. It covers +/-60{deg} in Galactic longitude... -
Submillimeter spectrum of HCOOCD_2_H
Astronomical surveys of interstellar molecules, such as those that will be available with the very sensitive ALMA telescope, require preliminary laboratory investigations of the... -
Gas dynamics in Massive Dense Cores in Cygnus-X
We studied the kinematic properties of dense gas surrounding massive protostars in a sample of five Massive Dense Cores (MDCs) in Cygnus-X. The aim is to investigate whether... -
Star formation in Perseus. II.
Hatchell et al. (2005, Cat. , Paper I) published a submillimetre continuum map of the Perseus molecular cloud, detecting the starless and protostellar cores within it. The aim... -
Observations at 850um in Perseus clusters
We present a complete survey of current star formation in the Perseus molecular cloud, made at 850 and 450{mu} with SCUBA at the JCMT. Covering 3deg^2^, this submillimetre... -
TMRT Ka-band (26.1-35GHz) obs. of Orion-KL
We conducted a Ka-band (26.1-35GHz) line survey toward Orion KL using the TianMa 65m Radio Telescope (TMRT). It is the first blind line survey in the Ka band and achieves a...
