IAU Symposium 360 Astropol2020 “onsite + online” new dates

Dear colleagues, 　

  First and foremost, we hope you, your family and friends are all well and managing through these tough times.  

 The COVID-19 pandemic is still a big issue worldwide.  Our daily lives has dramatically changed due to the pandemic.  

Considering the fact that it would not end anytime soon, we decided to hold  IAU Symposium 360 Astropol2020 in a hybrid mode, namely at Hiroshima physically along with online (realtime access plus video).  

  For those of you who can participate the symposium this time, we will ask all of you to register with new system when it’s ready.  We expect that the new system will become available in early October (next month) 2020.  

  For those of you who registered and already paid for the registration fee last time, you will be refunded with full amount.  Please give us some time to process it (to be completed by the end of this year).  

 We want to thank *you* in advance for your support and enthusiasm to the field of astronomical polarimetry. We look forward to your submissions and participation.  With your contributions, we will be able to make this symposium a true success, in spite of many difficulties that we need to overcome.

 Please stay in touch.  We will keep you updated.  

Sincerely, 

On behalf of the organizing committee,

IAUS 360 Astropol2020 SOC: Hiroko Shinnaga,

Astronomical Polarimetry 2020 (Astropol 2020) is the next in a series of 
international conferences. The aim of this series of conferences is to bring 
researchers interested in astronomical polarimetry together to share and
discuss recent results and advances in technical and scientific aspects 
in all relevant astronomical fields. This will be the first time that an Astropol symposium will take place in Asia. 

—
We will have following five sessions, as planned originally.  We invite your contributions on each topics:

[I.] Instrumentation and Techniques 

[II.] Sun, Solar System, and Exoplanets

[III.] ISM, Molecular clouds, Star formation 

[IV.]  Stars: Circumstellar Matter, Winds and Jets

[V.]  Extragalactic Polarimetry, CMB

Scientific Rationale

Astronomical Polarimetry 2020 (Astropol 2020) is the next in a series of international conferences. The aim of this series of conferences is to bring researchers interested in astronomical polarimetry together to share and discuss recent results and advances in technical and scientific aspects in all relevant astronomical fields.

It has been more than 60 years since Hall and Hiltner reported that the light from reddened stars is generally polarized. Around the same time, Davis and Greenstein presented a model to interpret the phenomena owing to aligned dust grains in the interstellar medium.

Since then, the global astronomical polarimetry community has grown tremendously. These cutting-edgetechniques are applied to answer major questions in astronomy, from small scales such as dust particles in proto-planetary systems up to large scales involving the origin and the fate of the Universe. Theories and models to interpret the observations have similarly evolved in scope and sophistication.

The first ‘Astropol’ conference was held in Tucson, AZ, in1972. After that, meetings were held in 1995 in Troy, New York, USA and in 2004 in Waikoloa, Hawaii. In the 2008 meeting in La Malbaie, Quebec, Canada, sciences cases from small to large telescopes were discussed, and the 2014 meeting in Grenoble, France covered wider fields of astronomical polarimetry, including laboratory experiments, solar system, exoplanets, stellar magnetic fields, interstellar medium, galaxies, Gamma-ray bursts and the Cosmic Microwave Background. This latest Astropol meeting attracted around 150 of participants.

Since 2014, a number of sophisticated instruments and datasets have become available to the community. ALMA was inaugurated in and started polarization observations in 2014. Adaptive optics aided 8-m class telescopes, such as Subaru, VLT and Gemini have been providing high-contrast spectropolarimetry. There is also the Robert Stobie Spectrograph (RSS) spectropolarimeter on the 11-m SALT telescope and the mid-infrared CanariCam polarimeter on the Gran Telescopio Canarias (GTC), that may become available to public in the future. Data release of the all-sky radio and submillimeter polarization mapping by the Planck satellite has had a strong impact in many astronomical fields. The SOFIA/HAWC+ FIR polarimeter is available to the community. In addition, Astrosat and Hitomi and balloon experiments have offered us new insights into the polarized sky in X-rays and Gamma-rays.

ASTROPOL 2020 will demonstrate that a new era of polarimetry has come to the astronomical community.
