Principal topics

Stellar magnetic fields, atomic diffusion, convection, rotation and pulsations are keys to the general understanding of stars and their evolution. The chemically peculiar (CP) stars provide unique environments in which these physical phenomena interact, both internally and in the atmospheric layers, leaving a multitude of signatures that can be studied using different kinds of observations and techniques. Topics:

  • recent observations and modeling of CP stars as the starting point for a multi-disciplinary exchange of ideas focused on the interpretation of the convolved effects of magnetism, pulsations, convection, rotation, and diffusion, in an evolutionary context

  • current and future ground and space-based observations of CP stars

  • atmospheric modelling and atmospheric mapping in the context of CP stars

  • understanding the CP and related phenomena in the context of stellar evolution.

Principal topics

Sophisticated dynamical models will be required to extract science from the large surveys of the Milky Way that will culminate in the Gaia survey (2012-2017). JD5 will review:

  • the kinds of data that are available to constrain such models

  • the various types of dynamical model that could be constructed

  • strategies for fitting models to the data, and

  • the nature of the computational challenge that these processes will entail.

The aims of JD5 are to clarify the work that must be accomplished, and to get the community working collaboratively towards the overall long-term goal.

Principal topics

  • the origin of the astrophysical jets and their effects on the astrophysical environments

  • understanding the driving mechanisms of jets from proto-stars (including their possible crucial link with star and planet formation) to microquasars and AGNs

  • the basic physics of the accretion-jet process in magnetized disks, including the transport of angular momentum and the development of reconnection and turbulent dynamo

  • cooling/heating processes, instabilities, shock structures and particle acceleration mechanisms in the jets

  • the impact of the jets on energy balance and turbulence feeding in the astrophysical environments
