  2. J0600 appears to be a repeating eclipse! Bradley Schaefer at LSU reports in ATel #13450 that there was an eclipse in late 1937 that lasted one month - so, 82 years, or 41, 27, 20 or 16 years! Very exciting...

    This is an excellent and clearly written thread on the perils of using 1D spectral retrievals on exoplanets with 2D atmospheric inhomogeneities (i.e. all of them) - caveat emptor!

    Best use of AR I've seen so far! Wowza :)

    Apodized Vortex Coronagraph showing 2e-8 from 6 to 10 diffraction widths in the lab - high contrast is tough! Llop-Sayson+ "High-contrast Demonstration of an Apodized Vortex Coronagraph"

    When I was a child and the teacher called on me to answer a question in front of the class and I had absolutely no clue what to say, this is what I must have sounded like to everyone else.

    1/ Friends, physicists, twitterers, lend me your ears; I come to bury samarium hexaboride, not to praise it. This is a (long, sorry) thread about my recent theoretical findings about samarium hexaboride, the "paradoxical crystal" with "exotic quantum behavior."

    ...and in classic esprit d'escalier, it should have been S'ZER, dammit.

    We only have ourselves to blame if an alien ship turns up in 2238 called SPZR.

    Excellent talk by at on monitoring variability of exoplanets using a gvAPP coronagraph!

    Hey! New Horizons is so far away that Proxima Cen shifts by 32 arcsec and Wolf 359 by 16, and we're going to show that by taking images of their fields on April 22-23 and comparing them to simultaneous Earth-based images.
