1. Ecole "Space-Inn school on astero/helioseismology and stellar/Solar physics" - 26-28 octobre 2015, Saclay
2. Workshop "X-ray surveys with advanced multi-wavelength cross-identification methods" - 30 novembre-2 décembre 2015, Paris

1. Ecole "Space-Inn school on astero/helioseismology and stellar/Solar physics" - 26-28 octobre 2015, Saclay

The school will be in Service d’Astrophysique, in Saclay (south of Paris), France

Each day will have a main topic, split between Lectures in the morning for about 3 to 4 hours and then "Hands on Computer" for the reminder of the day. Coffee breaks and lunches will be complementary with no registration fees.

Day 1 :
Stellar Internal Wave Physics by Dr. S. Mathis & Prof. M. Thompson
Lectures on the physics of waves inside stars (p, g modes, gravity-inertia-alfvenic waves) and on inversion techniques in (helio)seismology
Hands on computer : attendant will learn to develop a general p/g mode ray tracing code
Day 2 :
Asteroseismology by Dr. R.A. Garcia & Dr. E. Corsaro
Lectures on Kepler and Corot light curves and discoveries, rotation and magnetism proxies, data signal analysis and ensemble asteroseismology
Hands on computer : data analysis of Kepler/Corot and SoHO/GOLF light curves
Day 3 :
Stellar Dynamo and Wind by Dr. A.S. Brun and V. Reville
Lectures on the origin of solar and stellar magnetism, dynamo theory, the interplay between convection, rotation and magnetism and solar/stellar wind physics
Hands on computer : choose between the development of a 2-D mean field cartesian dynamo code or of a 2-D Parker-like wind model

The students will learn waves physics, use it to interpret light curves and make the link with the source of stellar variability and rotation history via stellar dynamo and wind theory.

For interested applicants, please send an email to both Sacha Brun and Rafael Garcia.

2. Workshop "X-ray surveys with advanced multi-wavelength cross-identification methods" - 30 novembre-2 décembre 2015, Paris

The workshop aims at presenting the main scientific issues addressed by large scale X-ray surveys carried out at high and low galactic latitudes and at discussing advanced probabilistic multi-catalogue cross-correlation algorithms applicable to both unresolved and extended sources. Together with spectral energy distribution building methods, these tools are essential to make best use of the fast-growing production of multi-wavelength archival data.

The workshop consists of 3 sessions, focused around X-ray surveys of AGN, clusters of galaxies and the Milky Way/galactic plane, with introductory reviews and contributed talks in each session. A fourth session is devoted to a discussion of the methods currently available and of some of the complexities involved in the simultaneous statistical cross-correlation of several catalogues.

The workshop will also be the opportunity to offer a half-day hands-on training with the tools produced by the ARCHES project. This event, while open to anyone, is particularly aimed at younger researchers.

Abstract submission deadline : 21 September 2015
