, 2007 We present observations of rotational lines of H2S, SO and CS performed in comet C/1995 O1 (Hale-Bopp) in March 1997 with the Plateau de Bure interferometer (IRAM).

Evolution of PAHs in photodissociation regions: Hydrogenation and charge states
, 2013 Various studies have emphasized variations of the charge state and composition of the interstellar polycyclic aromatic hydrocarbon (PAH) population in photodissociation regions (PDRs). We aim to model the spatial evolution of the charge and hydrogenation

, 2010 We explore the effects of photodissociation at the stages of post-asymptotic giant branch stars to find a mechanism able to produce multi-polar shapes. We perform two-dimensional gasdynamical simulations to model the effects of photodissociation in proto-

Sigma*-mediated electronic relaxation in 200nm photoexcited ammonia and heteroaromatics
EPJ Web of Conferences, 2013 Time–resolved photoelectron spectra of ammonia display combination bands of the umbrella and stretching modes associated with the N–H coordinate of σ* relaxation. Time–resolved photodissociation studies determine timescales

Dust processing in photodissociation regions - Mid-IR emission modelling
, 2008 Mid-infrared spectroscopy of dense illuminated ridges (or photodissociation regions, PDRs) suggests dust evolution. Such evolution must be reflected in the gas physical properties through processes like photo-electric heating or H_2 formation.

Photodissociation dynamics of HCOOH(Ã)
Chemical Physics Letters, 1988 The technique of Doppler-resolved, polarised LIF spectroscopy has been employed in a study of the energy and momenta disposal in the OH fragments generated via photodissociation of HCOOH (A 1A″) at 225 nm. The majority of the excess energy resides in fragment translation (≈ 78%) and internal excitation of the HCO fragment (≈ 12%).

Big-Bang Nucleosynthesis and Hadronic Decay of Long-Lived Massive Particles
, 2004 We study the big-bang nucleosynthesis (BBN) with the long-lived exotic particle, called X. If the lifetime of X is longer than \sim 0.1 sec, its decay may cause non-thermal nuclear reactions during or after the BBN, altering the predictions of the ...
