Context. Monoceros R2 (Mon R2), at a distance of 830 pc, is the only ultra-compact H ii region (UC H ii) where its associated photon-dominated region (PDR) can be resolved with the Herschel Space Observatory. Aims. Our aim is to investigate observationally the kinematical patterns in the interface regions (i.e., the transition from atomic to molecular gas) associated with Mon R2. Methods. We used the HIFI instrument on board Herschel to observe the line profiles of the reactive ions CH + ,O H…

Abundances of sulphur molecules in the Horsehead nebula First NS+ detection in a photodissociation region.
TLDR
This is the first complete study of S- bearing species towards a PDR and shows that CS, SO, and H2S are the most abundant S-bearing molecules in the PDR with abundances of ∼ a few 10-9.
OH+ IN ASTROPHYSICAL MEDIA: STATE-TO-STATE FORMATION RATES, EINSTEIN COEFFICIENTS AND INELASTIC COLLISION RATES WITH He
The rate constants required to model the OH+ observations in different regions of the interstellar medium have been determined using state of the art quantum methods. First, state-to-state rate
Bringing high spatial resolution to the far-infrared
TLDR
The velocity-resolved data in these tracers will reveal the detailed dynamics engrained in these processes in a spatially resolved fashion, and will deliver the perfect synergy with ground-based molecular line data for the colder dense gas.
Molecular tracers of radiative feedback in Orion (OMC-1) Widespread CH+ (J = 1-0), CO (10-9), HCN (6-5), and HCO+ (6-5) emission.
Young massive stars regulate the physical conditions, ionization, and fate of their natal molecular cloud and surroundings. It is important to find tracers that help quantifying the stellar feedback
Formation of interstellar SH+from vibrationally excited H2: Quantum study of S++ H2⇄ SH++ H reaction and inelastic collision
The rate constants for the formation, destruction, and collisional excitation of SH+are calculated from quantum mechanical approaches using two new SH+2potential energy surfaces (PESs) of4A″ and2A″
Isentropic thermal instability in atomic surface layers of photodissociation regions
We consider the evolution of an isentropic thermal instability in the atomic zone of a photodissociation region (PDR). In this zone, gas heating and cooling are associated mainly with photoelectric
From forced collapse to H ii region expansion in Mon R2: Envelope density structure and age determination with Herschel
The surroundings of HII regions can have a profound influence on their development, morphology, and evolution. This paper explores the effect of the environment on H II regions in the MonR2 molecular
The far-infrared spectroscopic surveyor (FIRSS)
TLDR
The Far Infrared Spectroscopic Surveyor (FIRSS) fulfills the requirements of a dedicated space-borne, far-infrared spectroscopic facility and by exploiting the legacy of recent photometric surveys it seizes the opportunity to shed light on the fundamental building processes of the authors' Universe.
On the Possible Formation and Destruction of the OD+ Ions in the Interstellar Medium.
TLDR
The formation and destruction of OD is found to be less efficient than that of OH and the OD/OH abundance ratio in ISM has been evaluated from a simple astrochemical model and it is found that this ratio can be larger than D/H abundance ratio only at low temperatures.
Dynamics of cluster-forming hub-filament systems: The case of the high-mass star-forming complex Monoceros R2.
TLDR
It is estimated that with the observed infall velocity, the mass-doubling time of the hub is ~ 2:5 Myr, ten times larger than the free-fall time, suggesting a dynamically old region.
