To date, 204 individual molecular species, comprised of 16 different elements, have been detected in the interstellar and circumstellar medium by astronomical observations. These molecules range in size from 2 atoms to 70, and have been detected across the electromagnetic spectrum from centimeter wavelengths to the ultraviolet. This census presents a summary of the first detection of each molecular species, including the observational facility, wavelength range, transitions, and enabling…

To date, 241 individual molecular species, composed of 19 different elements, have been detected in the interstellar and circumstellar medium by astronomical observations. These molecules range in

Molecules in the Carbon-rich Protoplanetary Nebula CRL 2688

We present observations of the carbon-rich protoplanetary nebula CRL 2688 made with the Institut de Radioastronomie Millimétrique 30 m telescope in the 3 and 2 mm bands. In total, 196 transition

Laboratory data in support of JWST observations of interstellar ices

Abstract Experimental and theoretical studies have shown that Complex Organic Molecules (COMs) can be formed on icy dusty grains in molecular clouds and protoplanetary disks. The number of

Organic Molecules in Interstellar Space: Latest Advances

Although first considered as too diluted for the formation of molecules in-situ and too harsh an environment for their survival, the interstellar medium has turned out to host a rich palette of

Galactic and Extragalactic Astrochemistry : Heavy-Molecule Precursors to Life ?

  • Physics, Chemistry
  • 2019
Heavy molecule spectroscopy is a developing subject, with new results from both the terrestrial laboratory and astronomical discovery in the 0.5-10 GHz range where heavy molecule spectral lines are

An Unbiased ALMA Spectral Survey of the LkCa 15 and MWC 480 Protoplanetary Disks

The volatile contents of protoplanetary disks both set the potential for planetary chemistry and provide valuable probes of defining disk system characteristics such as stellar mass, gas mass,

A Search for Light Hydrides in the Envelopes of Evolved Stars

We report a search for the diatomic hydrides SiH, PH, and FeH along the line of sight toward the chemically rich circumstellar envelopes of IRC+10216 and VY Canis Majoris. These molecules are thought

Searches for Interstellar HCCSH and H2CCS

A longstanding problem in astrochemistry is the inability of many current models to account for missing sulfur content. Many relatively simple species that may be good candidates to sequester sulfur

Astrochemistry With the Orbiting Astronomical Satellite for Investigating Stellar Systems

Chemistry along the star- and planet-formation sequence regulates how prebiotic building blocks—carriers of the elements CHNOPS—are incorporated into nascent planetesimals and planets. Spectral line

Detection of an Extrasolar Planet Atmosphere

We report high-precision spectrophotometric observations of four planetary transits of HD 209458, in the region of the sodium resonance doublet at 589.3 nm. We find that the photometric dimming

First detections of extragalactic SO2, NS and NO

We report the first detections of SO 2 , NS and NO in an extragalactic source, the nucleus of the starburst galaxy NGC 253. Five SO 2 transitions, three groups of hyperfine components of NO and five

Chemistry in disks

Context. Several sulfur-bearing molecules are observed in the interstellar medium and in comets, in strong contrast to protoplanetary disks where only CS, H2CS, and SO have been detected so far.

Detection of Interstellar OH in Two External Galaxies

Abstract : Molecular OH lines at 1665 and 1667 MHz have been detected in absorption in the spiral galaxy NGC 253 and the irregular galaxy M82. This is the first time interstellar molecular lines,

Detection of Interstellar PN: The First Identified Phosphorus Compound in the Interstellar Medium

Interstellar PN has been identified in Ori (KL), W51M, and Sgr B2, by observations of its J = 2-1, 3-2, and 5-4 rotational transitions. PN appears to occur in regions of relatively high excitation,

First Detection of the Simplest Organic Acid in a Protoplanetary Disk

The formation of asteroids, comets, and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition of the disk might shape

DETECTION OF CH4 IN THE GV TAU N PROTOPLANETARY DISK

T Tauri stars are low mass young stars that may serve as analogs to the early solar system. Observations of organic molecules in the protoplanetary disks surrounding T Tauri stars are important for

Detection of extragalactic H3O

Context. The H3O+ molecule probes the oxygen chemistry and the ionization rate of dense circumnuclear gas in galaxies. Aims. Recent H3O+ observations show variations in the cosmic-ray ionization

Observations of the Icy Universe

Freeze-out of the gas-phase elements onto cold grains in dense interstellar and circumstellar media builds up ice mantles consisting of molecules that are mostly formed in situ (H2O, NH3, CO2, CO,

Detection of extragalactic argonium, ArH + , toward PKS 1830-211

Context. Argonium has recently been detected as a ubiquitous molecule in our Galaxy. Model calculations indicate that its abundance peaks at molecular fractions in the range of 10^(-4) to 10^(-3) and
