To understand how phosphorus (P)-bearing molecules are formed in star-forming regions, we have analysed the Atacama Large Millimeter/Submillimeter Array (ALMA) observations of PN and PO towards the massive star-forming region AFGL 5142, combined with a new analysis of the data of the comet 67P/Churyumov–Gerasimenko taken with the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument onboard Rosetta. The ALMA maps show that the emission of PN and PO arises from several… 
First Images of Phosphorus Molecules toward a Protosolar Analog
The chemistry of phosphorus in star- and planet-forming regions is poorly understood, despite the central role of phosphorus in terrestrial biochemistry. We present Atacama Large
Probing the Chemistry of P-Bearing Molecules in Interstellar Environments and other Extraterrestrial Environments
<p>Phosphorus is one of the most important elements in biochemistry together with carbon, oxygen, hydrogen and nitrogen. Therefore, P-bearing compounds with some prebiotic potential and their
Chemical Complexity of Phosphorous-bearing Species in Various Regions of the Interstellar Medium
Phosphorus-related species are not known to be as omnipresent in space as hydrogen, carbon, nitrogen, oxygen, and sulfur-bearing species. Astronomers spotted very few P-bearing molecules in the
Ionize Hard: Interstellar PO+ Detection
We report the first detection of the phosphorus monoxide ion (PO+) in the interstellar medium. Our unbiased and very sensitive spectral survey toward the G+0.693–0.027 molecular cloud covers four
Detection of PO in Orion-KL: Phosphorus Chemistry in the Plateau Outflow
The PO molecule (X 2Πr) has been detected toward Orion-KL via its J = 2.5 → 1.5 transition near 109 GHz using the 12 m telescope of the Arizona Radio Observatory. This transition consists of a
The Chemical Nature of Orion Protostars: Are ORANGES Different from PEACHES? ORANGES II.
Understanding the chemical past of our Sun and how life appeared on Earth is no mean feat. The best strategy we can adopt is to study newborn stars located in an environment similar to the one in
First survey of HCNH+ in high-mass star-forming cloud cores
Context. Most stars in the Galaxy, including the Sun, were born in high-mass star-forming regions. It is hence important to study the chemical processes in these regions to better understand the
The detection of solid phosphorus and fluorine in the dust from the coma of comet 67P/Churyumov–Gerasimenko
Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Ion Mass Analyser
Computational Study of the Hydrogenation Sequence of the Phosphorous Atom on Interstellar Dust Grains
The detection of phosphorous-bearing molecules in interstellar environments constitutes a fundamental task for understanding the formation of prebiotic molecules, but it is also a challenge. In cold
Formation of Phosphorus Monoxide (PO) in the Interstellar Medium: Insights from Quantum-chemical and Kinetic Calculations
In recent years, phosphorus monoxide (PO), an important molecule for prebiotic chemistry, has been detected in star-forming regions and in the comet 67P/Churyumov-Gerasimenko. These studies have


Phosphorus-bearing molecules in massive dense cores
Phosphorus is a crucial element for the development of life, but so far P-bearing molecules have been detected only in a few astrophysical objects, hence its interstellar chemistry is almost totally
Detection of Phosphorus-bearing Molecules toward a Solar-type Protostar
Phosphorus is a key ingredient in terrestrial biochemistry, but is rarely observed in the molecular ISM and therefore little is known about how it is inherited during the star and planet formation
PO and PN in the wind of the oxygen-rich AGB star IK Tauri
Phosphorus-bearing compounds have only been studied in the circumstellar environments (CSEs) of the asymptotic giant branch (AGB) star IRC +10216 and the protoplanetary nebula CRL 2688, both C-rich
Phosphorus in the Young Supernova Remnant Cassiopeia A
Near-infrared spectroscopic observations of the young SN remnant Cassiopeia A show that the abundance ratio of phosphorus to the major nucleosynthetic product iron in SN material is up to 100 times the average ratio of the Milky Way, confirming that phosphorus is produced in SNe.
Phosphorus-bearing molecules in the Galactic Center
Phosphorus (P) is one of the essential elements for life due to its central role in biochemical processes. Recent searches have shown that P-bearing molecules (in particular PN and PO) are present in
The Chemistry of Phosphorus-bearing Molecules under Energetic Phenomena
For decades, the detection of phosphorus-bearing molecules in the interstellar medium was restricted to high-mass star-forming regions (as e.g. SgrB2 and Orion KL) and the circumstellar envelopes of
On the origin of phosphorus nitride in star-forming regions
We present multi-transition observations of PN towards a sample of nine massive dense cores in different evolutionary stages. Using transitions with different excitation conditions, we have found for
Molecular nitrogen in comet 67P/Churyumov-Gerasimenko indicates a low formation temperature
Direct measurements of N2 by instruments aboard the Rosetta spacecraft provide clues about the comet’s long history and depletion of molecular nitrogen at levels that are depleted compared to those in the primordial solar system suggests that the comet formed at low-temperature conditions below ~30 kelvin.
Detection of phosphorus nitride in the Lynds 1157 B1 shocked region
We have observed the J = 2–1 rotational emission line of PN toward the low-mass star forming region L 1157 with the Nobeyama 45 m telescope. The PN line has been detected toward the two shocked
Phosphorus in the dense interstellar medium
An observational study was made of interstellar (and circumstellar) phosphorus chemistry by means of (1) a survey of PN in energetic star-forming regions (several new detections); (2) a search for PN
