Stellar modeling: * stellar evolution models for massive, intermediate and low mass stars including mass loss, stellar rotation, and gravity waves [AM, GM, CC] * stellar atmospheres and radiation transfer: atmosphere models for O stars including stellar winds, non-LTE effects, and line blanketing [DS] - Nucleosynthesis, stellar yields: * hydrostatic phases of massive stars (pre-SN modeling in progress) [AM, GM] * nucleosynthesis origin of CNO, Ne, 26Al and related elements/isotopes in the proto-solar nebula, the local interstellar cloud, meteorites, stars, Galactic regions, and extragalactic objects [AM, GM, CC] * studies of the primordial Li and 3He abundances, nucleosynthesis in intermediate and low mass stars, stellar abundances in globular clusters and Local Group galaxies [CC] - Evolutionary synthesis modeling: * development of multi-wevelength synthesis codes [DS] * combined starburst - photoionisation modeling [DS] * ISM radiation transfer modeling (in progress) [DS] - Studies of stellar populations: * (resolved) massive star populations in Local Group galaxies [AM, GM] * multi-wavelength studies of Galactic massive star forming regions (gamma, UV, optical, IR, radio) [DS] * massive star populations in starbursts, UV-optical studies of Wolf-Rayet galaxies [DS] * mid-IR studies of young starbursts [LMH, DS] - Stellar clusters: * WEBDA Database of Galactic Open Clusters [JCM] * analysis of young stellar clusters and confrontation with stellar evolution models [JCM, GM] * spectroscopic studies of stars in galacic globular clusters [CC] - N-body and hydrodynamical modeling: * galaxy modeling [DP] * collapse models combining hydrodynamics, gravity, chemistry and radiation transfer [DP] Involvement in observational/instrumental projects related to RTN ----------------------------------------------------------------- - High energy astrophysics: * PI of INTEGRAL Science Data Center (ISDC) hosted by the Geneva Observatory [TC] - FLAMES/VLT: CoI institute, group of [AB] - KMOS/VLT: member of consortium, and member of science team of near-IR multi object spectrograph "KMOS-2" proposed for 2nd generation instrumentation on VLT [DS] Proposed topics for research and formation ------------------------------------------ Possible in main domains of expertise listed above, in particular: - stellar evolution modeling including diffusion, rotation, gravitational waves, and magnetic fields - radiation transfer modeling in galaxies - combined photoionisation and dust emission modeling - mid-IR studies high resolution of starburst galaxies - stellar population studies of nearby to distant starbursts (observations and modeling) - chemical evolution studies Also: - high redshift starbursts and Population III objects (modeling and observational programs) - hydrodynamic modeling of SF in early Universe For all topics studies at the pre- or post-doctoral level can be proposed. Most of these topics could greatly benefit from shared expertise with other proposed RTN members within and beyond ongoing collaborations. This includes both expertise with observations and modeling.
