Hello everyone,

In case you didn’t hear the news, Dr. Quarles is a co-author to one of two newly accepted papers that provide strong evidence for a potential planet around Alpha Cen A.  Dr. Quarles’s contributions focused on the orbital modeling crucial to explaining the non-detection of the planet in some of the images.

A university press release about the discovery is here:

And the paper itself is worth a read as well.  (See section 2 for an explanation of the many trials and tribulations of trying to image a putative planet.)

Congrats Billy!

Cheers,
