... Future seminars . ... Magnetic field generation during accretion into black holes " . ... The problem of magnetic field generation in accretion flows onto black holes is discussed, including the field amplification in the falling gas, and due to the action of the excess radiation force on electrons. ... Instead of a recent claim of the generation of dynamically important magnetic fields, we establish the validity of earlier results from 1977 which show only small magnetic fields are generated. ...

... Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: The role of magnetic fields in the intermediate-mass star formation process . ... Spectropolarimetric observations of Herbig Ae/Be stars indicate that magnetic fields are important ingredients of intermediate mass star formation. To properly understand the physics involved in the intermediate mass star formation process, it is particularly important to know the origin of the magnetic fields in these stars. ...

... Triggered Star Formation . ... It is now well established that massive stars in star forming regions can trigger next generation of star formation. ... The young stellar objects (YSOs) in star forming regions have been identified using the near-infrared (NIR) and mid-infrared (MIR) observations. ... The age of YSOs, the morphology of the regions and the global distribution of YSOs indicate that the star formation can be triggered by either (RDI/ CC) of the processes. ...

Local galaxies are in a state of energy equipartition which means that the kinetic energy density equals roughly the thermal one and the magnetic one. ... In models of young galaxies magnetic fields are usually not considered as they are assumed not to be dynamical important at high redshifts. In the presence of turbulence, however, the turbulent dynamo can amplify weak magnetic seed fields by randomly stretching, twisting, and folding the field lines. ...

Top] [Prev] [Next] . We will present a general overview of protostellar evolution in the context of planet formation, with a review of the "standard model" for star formation, which considers a single star forming in isolation. ... Since present technology allows us to discover and study disks in more detail than is yet possible for planets themselves, disks around young stars have much to tell us about the process of planet formation. ...

... ALMA . ... OOF software . ... Software . ... We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. Notable features are simulating three dimensional turbulent volumes instead of flat phase screens, considering three representative configurations of ALMA and parametrisation in terms of phase fluctuations on a 300m baseline, allowing referencing to the site-testing interferometer data. ...

... Program,Proceedings . ... Abstracts . ... The main purpose of the Workshop is to provide a forum for presenting and discussing the results of recent low temperature investigations in the microgravity environment, as well as future related studies in fundamental physics that can be carried out on ground and onboard the International Space Station, taking into account the advantage of long-duration experimentation in reduced gravity. ...

... Future seminars . P a s t seminars . Seminar council . Physical Processes in a Dusty Ionospheric Plasma " . S.I. Popel ( Institute for Dynamics of Geospheres RAS ) . ... Processes of formation of a dusty ionospheric plasma and physical processes in the plasma are discussed. ... A self-consistent model of the dusty ionosphere which allows for grain growth, sedimentation, and charging is developed. ... Wave properties of the dusty ionosphere are also discussed. ...

Direct Electron Imaging Using Back Thinned CCDs . ... A proximity focused Gen III image intensifier has been built using a back illuminated 512 x 512 CCD in place of the phosphor screen. Signal to noise, spatial resolution, minimum resolvable signal and life are discussed. ... Very low light level imaging is driven by the need for high quantum efficiency detection of single photons at the highest possible speed and the highest spatial resolution. ...
