May 25, 2015. The 3rd SOLARNET Workshop "Polarization in the Sun, the Solar System, and Beyond" started in Granada, Spain.

The 3rd SOLARNET Workshop “Polarization in the Sun, the Solar System, and Beyond” has been started today in Granada (Spain). This four days even (25-28 May 2015) is organized by the Instituto de Astrofísica de Andalucía (IAA-CSIC) under the auspices of SOLARNET.

The goal of this workshop is to present the latest advances in astronomical polarimetry and spectropolarimetry, with a focus on the sun, solar system bodies, stars, and exoplanets, and also to bring together the different communities and fostering collaborations between them.

In order to provide a detailed account of the latest developments in these areas -including instrumentation, measurement techniques, data analysis and interpretation- the following sessions have been scheduled:    Instrumentation (ground, space, laboratory)

  •     Diagnostics and Interpretation
  •     Solar Photosphere
  •     Solar Chromosphere, Transition Region, and Corona
  •     Polarization in the Solar System and Exoplanetary Systems
  •     Stellar Magnetic Fields

The workshop is being carried out right after the 3rd SOLARNET School on “Solar Magnetic Fields: Modeling and Measuring Techniques," which also took place the last week in Granada, Spain.

May 18, 2015. The 3rd SOLARNET School started in Granada, Spain.

The 3rd SOLARNET School “Solar Magnetic Fields: Modeling and Measuring Techniques” has been opened today in Granada, Spain.

SOLARNET Project prioritizes the collaborations between the new generation of scientists and experienced researchers through short stays and training actions to acquire competences in relevant fields of Solar Physics.

Under the auspices of SOLARNET, and organised by our partners from the Instituto de Astrofísica de Andalucía (IAA-CSIC), the School is dedicated to PhD students and novel post-doctoral researchers.

This international school aims at providing PhD students and early career researchers with a solid background in solar spectropolarimetry, radiative transfer of polarized light, and diagnostic techniques. The school program combines theory and hands-on activities to achieve this goal. The latter will focus on the use of inversion codes such as SIR, NICOLE, and HAZEL, so that the participants can apply these tools to their own observation.

The lectures and hands-on sessions will be carried out by experienced scientists, and will allow the 26 participating students -from Europe, India, China and Colombia- to enrich their knowledge in Solar Physics.

3rd SOLARNET School - Granada 2015

The school will consist of three main courses:

  • Solar polarization measurements: instruments and techniques (Lecturer: Bruce Lites, HAO, USA)
  • Spectral line formation in the presence of magnetic fields (Lecturer: Jose Carlos del Toro Iniesta, IAA-CSIC, Spain)
  • Solar magnetic fields: diagnostics and applications (Lecturer: Andrés Asensio Ramos, IAC, Spain).

These courses will be complemented with three hands-on sessions:

  • Stokes inversions under LTE conditions: SIR (Luis Bellot Rubio, IAA-CSIC, Spain)
  • Stokes inversions under non-LTE conditions: NICOLE (Jaime de la Cruz Rodríguez, ISP, Stockholm University, Sweden)
  • Hanle and Zeeman inversion of spectral lines: HAZEL (Lecturer: David Orozco Suárez, IAC, Spain).

XXIX IAU General Assembly FM13: Brightness Variations of the Sun and Sun-like Stars.

The XXIX IAU General Assembly will be held August 3-14, 2015 in Honolulu, Hawaii.

We invite contributions to the Focus Meeting 13 “Brightness Variations of the Sun and Sun-like Stars” scheduled for August 5-6, 2015.

The Focus meeting will address the following key topics:

1. Measurements of solar irradiance variability.
2. Stellar variability on rotational time scales; Kepler and Corot measurements.
3. Stellar variability on activity cycle time scales; ground based observations.
4. Physical mechanisms and models of solar and stellar brightness variability.
5. The photometric signature of magnetic activity: darker or brighter?
6. Is the Sun a solar-type variable?
7. Constraining dynamo models using solar and stellar variability records.
8. Influence of solar and stellar variability on Earth and other planets.
9. Stellar variability as a limiting factor for detectability of extra-solar planets.


Session 1: Observing solar and stellar variability
Session 2: The solar-stellar connection
Session 3: Modelling solar and stellar variability
Session 4: The impact of solar and stellar variability on their environment
