Microlensing planets

Post #1by ajtribick » 03.06.2008, 19:48

This add-on requires SVN Celestia as it places stars beyond the 16kly limit

This add-on implements the exoplanets detected by gravitational microlensing. Implementation is fairly simple: the source and lens stars are modelled as lying in exactly the same straight line, the orbital radius is taken to be the projected separation, so use with caution. Planets are assumed to be Jovian for radius calculations, except OGLE-2005-BLG-169Lb which is given Neptune-like density, and OGLE-2005-BLG-390Lb and MOA-2007-BLG-192Lb are given Earthlike density.

Instructions: place the microlens.stc and microlens.ssc files in your extras directory.

Andrew,

I am a bit worried by the following:

as you are sure aware of, there are many /dramatic/ evidences of microlensing in the Universe. Are you not a bit worried that such a specialized visualization (as your add-on) generates a somewhat "narrow minded focus" of the matter? Microlensing always was an important general aspect of my cosmological extension plans and should really be done in a systematic manner. Don't you think? But of course, I have no intention to try and discourage you ;-) .

Yeah, but I'm an exoplanets geek. :D

That explains of course everything ;-)

In that case, I'm sure you will be interested in this recent addition: http://www.physorg.com/news131631686.html. (First discovered using microlensing at the Mt John Observatory in New Zealand)

You will note that it's in the add-on already. :) In fact, it was sort of the motivation for it in the first place.
