Comets and chondrites show non-monotonic behaviour of their Deuterium to Hydrogen (D/H) ratio as a function of their formation location from the Sun. This is difficult to explain with a classical protoplanetary disk model that has a decreasing temperature structure with radius from the Sun. We want to understand if a protoplanetary disc with a dead zone, a region of zero or low turbulence, can explain the measured D/H values in comets and chondrites. We use time snapshots of a vertically…

Disentangling hot Jupiters formation location from their chemical composition
We use a population synthesis model that includes pebbles and gas accretion, planetary migration, and a simplified chemistry scheme to study the formation of hot-Jupiters. Models have been proposed
What is Neptune's D/H ratio really telling us about its water abundance?
We investigate the deep water abundance of Neptune using a simple 2-component (core + envelope) toy model. The free parameters of the model are the total mass of heavy elements in the planet (Z), the
D/H in the refractory organics of comet 67P/Churyumov-Gerasimenko measured by Rosetta/COSIMA
The D/H ratio is a clue to the origin and evolution of hydrogen-bearing chemical species in Solar system materials. D/H has been observed in the coma of many comets, but most such measurements have


The edges of magnetically dead zones in protostellar disks have been proposed as locations where density bumps may arise, trapping planetesimals and helping form planets. Magneto-rotational
On the evolution of the snow line in protoplanetary discs – II. Analytic approximations
We examine the evolution of the snow line in a protoplanetary disc that contains a dead zone (a region of zero or low turbulence). The snow line is within a self-gravitating part of the dead zone,
Heating Protoplanetary Disk Atmospheres
We calculate the thermal-chemical structure of the gaseous atmospheres of the inner disks of T Tauri stars, starting from the density and dust temperature distributions derived by D’Alessio and
Astro- and cosmochemical consequences of accretion bursts - I. The D/H ratio of water
The D/H ratio of water in protostellar systems is a result of both inheritance from the parent molecular cloud and isotopic exchange in the disc. A possibly widespread feature of disc evolution,
Magnetorotational-instability-driven Accretion in Protoplanetary Disks
Non-ideal MHD effects play an important role in the gas dynamics in protoplanetary disks (PPDs). This paper addresses the influence of non-ideal MHD effects on the magnetorotational instability (MRI)
Constraints on the Formation of Comets from D/H Ratios Measured in H2O and HCN
This report is the follow-up of the paper of A. Drouart et al. (1999, Icarus140, 129) in which it was demonstrated that appropriate models of the solar nebula permit us to interpret the deuterium
The ionization fraction in α models of protoplanetary discs
We calculate the ionization fraction of protostellar a discs, taking into account vertical temperature structure and the possible presence of trace metal atoms. Both thermal and X-ray ionization are
