Astronomical Polarimetry 2014 (ASTROPOL 2014)


This is the second announcement for ASTRONOMICAL POLARIMETRY 2014. Registration and call for contributions are open. Please visit our website at: www.polarisation.eu/index.php/astropol-2014


The aim of ASTROPOL 2014 is to bring together all researchers interested in astronomical polarimetry to discuss the most recent results and advances, technical and scientific. The 2014 meeting will be co-organised by the European COST action "polarisation as a tool to study the solar system and beyond". See www.polarisation.eu.


Since 2008, spectacular astrophysical results using polarimetry were obtained in all fields, from the ground and from space, from the Cosmological Background, to galaxies, to nearby exoplanets and Solar System objects. New instruments are also coming on-line with ever improving polarimetric capacities: ALMA, and the high resolution planet finder instruments GPI on Gemini South and SPHERE on the ESO/VLT, to name just a few. Future instruments like SKA, LOFAR and the giant optical/NIR telescopes are also taking shape. This is a very exciting time for polarimetry and ASTROPOL 2014 promises to be just as exciting, rich in new results and technical advances. The conference is limited to 150 participants.


ASTROPOL 2014 will be held at MINATEC and WTC. Both are conveniently located near the train station and the main tramway line serving the city center. The conference rooms are modern, air conditioned, and adjacent to a large dining hall where coffee breaks and catered buffet for all participants will be provided every day. The same common space will also be used to keep posters on display for the full week, allowing for maximum exposure and lively scientific discussions.


An outline of the conference schedule is included below. The balance between sessions will evolve as a function of the number of oral contributions received. There will be ample room to present posters as well.

Please circulate this message to your colleagues. We hope to see many of you in Grenoble

Asteroids, Comets, Meteors focuses on the research of small Solar System bodies. Small bodies are the key to understanding the formation

and evolution of the Solar System, carrying signals from pre-solar times. Understanding the evolution of the Solar System helps unveil

the evolution of extrasolar planetary systems. Societally, small bodies will be important future resources of minerals. The near-Earth

population of small bodies continues to pose an impact hazard, whether it be small pieces of falling meteorites or larger asteroids or

cometary nuclei capable of causing global environmental effects.


ACM'2014 hosts a special workshop on Absorption, Scattering, and Emission of electromagnetic radiation from the surfaces of asteroids and cometary nuclei, cometary comae and tails composed of dust particles, as well as from meteoroids, meteors, and meteorites. Direct and inverse problems in polarimetry, photometry, and spectroscopy are assessed using observational, experimental, numerical, and theoretical methods.


The conference series entitled "Asteroids, Comets, Meteors" constitutes the leading international series in the field of small Solar System bodies. The first three conferences took place in Uppsala, Sweden in 1983, 1985, and 1989. The conference is now returning to Nordic countries after a quarter of a century. After the Uppsala conferences, the conference has taken place in Flagstaff, Arizona, U.S.A. in 1991, Belgirate, Italy in 1993, Paris, France in

1996, Ithaca, New York, U.S.A. in 1999, in Berlin, Germany in 2002, in Rio de Janeiro, Brazil in 2005, in Baltimore, Maryland, U.S.A. in 2008, and in Niigata, Japan in 2012. ACM in Helsinki, Finland in 2014 will be the 12th conference in the series.


The ACM'2014 Call for Abstracts and Registration is now open at


(e-mail: acm-2014@helsinki.fi )


Abstracts and registration are due by March 31, 2014


Looking forward to seeing you in Helsinki,

ADDA news


Dear ADDA users,


On behalf of ADDA contributors I would like to bring your attention to the beta-version of ADDA (1.3b4). It has two exciting new features:

* Rigorous treatment of particles near the infinite plane surface with full 3D-FFT acceleration.

* Use of point-dipole incident field, which enables calculation of dipole decay-rate enhancement.


An extensive changelog is available at doc/history. If you would like to test these new features and/or use it in your research, please download the ADDA package (both main package and, if needed, executable for 32- and 64-bit Windows) from: http://code.google.com/p/a-dda/wiki/Downloads (mind that the latter address is different from the one used previously).


This version has received a standard (large) amount of pre-release testing, so it is, in principle, ready for production runs. Moreover, both new features were tested against alternative methods/implementations. See, e.g., http://code.google.com/p/a-dda/wiki/ComparisonOtherCodes#Particles_near_surface But we decided to make a beta-release, since we want to finish a few minor things before the final release and to collect your feedback on the new features. Also, we do not recommend you to upgrade to the new version unless you plan to use new features.


Development of ADDA has always relied on feedback of users. But now we specifically ask for your opinion. Not only on the correctness of the implementation (whether ADDA agrees with other methods), but also on the clarity of the manual, wiki page, and used definitions, as well as on the convenience of using the new features. Overall, it would be great if you can use the new features in the production (research) workflow and suggest how to improve user's experience.


Your feedback is welcome either at the discussion group - adda-discuss@googlegroups.com , or directly at the issue tracker, e.g.




Finally, please note that ADDA is an open-source project which development relies on the community around it. There are many ways to help:

* Using ADDA and advocating its use through publications and conference presentations. Please also consider citing the papers from the list http://code.google.com/p/a-dda/wiki/References .

* Active participation in the discussion group - http://groups.google.com/group/adda-discuss , in particular, sharing your experience with other users.

* Commenting and improving wiki pages ( http://code.google.com/p/a-dda/w/list ) and other documentation.

* Locating bugs and proposing new features for ADDA, using the issue tracker - http://code.google.com/p/a-dda/issues .

* Contributing and improving the source code - http://code.google.com/p/a-dda/wiki/InstructionCommitters .


Best regards,

Maxim Yurkin.
