Highlights from AAS Nova: 30 September - 13 October 2018

AAS Nova provides brief highlights of recently published articles from the AAS journals, i.e., The Astronomical Journal (AJ) and The Astrophysical Journal (ApJ), ApJ Letters, and ApJ Supplements. The website's intent is to gain broader exposure for AAS authors and to provide astronomy researchers and enthusiasts with summaries of recent, interesting research across a wide range of astronomical fields.

The following are the AAS Nova highlights from the past two weeks; follow the links to read more, or visit the AAS Nova webpage for more posts.
