The gas-phase reaction of $\mathrm{O}+\mathrm{H}_3^+$ has two exothermic product channels, $\mathrm{OH}^+ +\mathrm{H}_2$ and $\mathrm{H}_2\mathrm{O}^+ +\mathrm{H}$. In the present study, we analyze experimental data from a merged-beams measurement to derive thermal rate coefficients resolved by channel for temperature range 10 1000 K. Published astrochemical models either ignore second or apply...

Using the ground potential energy surface[M. Ayouz et al. J. Chem Phys 132 194309 (2010)] of the H−3 molecule, we have determined the energies and widths of the complex resonant levels of H−3 located up to 4000 cm −1 above the dissociation limit H−+H2(vd = 0, jd = 0). Bound and resonant levels of the H2D − and D2H − isotopologues have been also characterized within the same energy range. The me...

We explore the parameter space for contribution to Callisto's H corona observed by Hubble Space Telescope (Roth et al. 2017a) from sublimated H2O and radiolytically produced H2 using Direct Simulation Monte Carlo (DSMC) method. The spatial morphology of this via photo- magnetospheric electron impact-induced dissociation is described tracking motion simulating collisions between hot atoms therma...

This paper considers the design of robust, nite-horizon and innnite-horizon H 2 estima-tors based on multliplier theory (which is intimately related to the mixed structured singular value). Speciically, the Popov-Tsypkin multiplier is used to develop a novel upper bound on a nite-horizon, cost function for the assumed uncertainty set. The results are then applied to develop design equations for...
