An RAS Specialist Discussion meeting entitled "30 Years of Planetary Astronomy with H3+" will be held on 14 December 2018 at the Royal Astronomical Society at Burlington House. This meeting is co-convened by Steve Miller (UCL) and Nick Achilleos (UCL).
The RAS listing for the meeting is available here and the meeting abstract is as follows:
2018 marks the 30th anniversary of the serendipitous discovery of the H3+ molecular ion in Jupiter’s northern aurora. The discovery itself was the result of an impromptu collaboration between astronomical observers, telescope instrument builders, laboratory spectroscopists and molecular physicists. H3+ emission has subsequently been detected from Saturn and Uranus, of the Solar System’s giant planets, but not Neptune. As an energetic and reactive molecular ion, H3+ is now used as a tracer for energy inputs, via particle precipitation, into giant planets’ atmospheres from their enormous magnetospheres: variations in emission levels are used to monitor both shorter-term magnetospheric dynamics, caused by changes in internal (plasma density) and external (solar wind dynamic pressure) factors, and longer-term changes that may result from the solar cycle and seasonal changes in solar irradiation. The final results from Cassini – particularly the VIMS instrument – and new measurements from JUNO mean that there is a wealth of data to add to and complement that being generated from ground-based observations. All-in-all, there is a wealth of material to review and huge current interest in just how this simple molecular ion behaves and what it tells us about planets in our Solar System and beyond.
A new mailing list for space scientists who use Python has been founded. Angeline Burrell writes:
In the days of yesteryear, there was a MIST forum provided for members of the MIST community to discuss things in a fashion more immediate and informal than email. It has been some years since the fabled MIST forum was a going concern, and in that time, the MIST Council has technically been in violation of the MIST Charter, which states that
MIST will provide an on-line forum to allow ongoing discussions and the formulation of ideas prior to public dissemination. This forum will be private, visible only to registered members; membership is restricted to active MIST scientists and is offered at the discretion of MIST council chair.
