Highly structured inner planetary system debris around the intermediate age Sun-like star TYC 8830 410 1

We present detailed characterization of the extremely dusty main sequence star TYC 8830 410 1. This system hosts inner planetary system dust (Tdust~300 K) with a fractional infrared luminosity of ~1%. Mid-infrared spectroscopy reveals a strong, mildy-crystalline solid-state emission feature. TYC 8830 410 1 (spectral type G9V) has a 49.5" separation M4-type companion co-moving and co-distant with it, and we estimate a system age of ~600 Myr. TYC 8830 410 1 also experiences "dipper"-like dimming events as detected by ASAS-SN, TESS, and characterized in more detail with the LCOGT. These recurring eclipses suggest at least one roughly star-sized cloud of dust orbits the star in addition to assorted smaller dust structures. The extreme properties of the material orbiting TYC 8830 410 1 point to dramatic dust-production mechanisms that likely included something similar to the giant-impact event thought to have formed the Earth-Moon system, although hundreds of millions of years after such processes are thought to have concluded in the solar system. TYC 8830 410 1 holds promise to deliver significant advances in our understanding of the origin, structure, and evolution of extremely dusty inner planetary systems.
