We recently had another article accepted for publication in the Astronomical Journal! A pre-print is now available here. This paper presents the discovery a nearby young brown dwarf with a disk, W1200-7845. Brown dwarfs are substellar objects that range in mass from about 13-80 Jupiter masses. They don’t have enough mass to sustain hydrogen burning in their cores, so they don’t qualify as stars, but they are just massive enough to burn molecular hydrogen (H2) in their cores, making them also distinct from planets. Understanding brown dwarfs is therefore key to understanding the connection betw ..read more

Hi, all: As you may have seen over the past month, or from today’s email blast from Zooniverse, Disk Detective v2.0 is LIVE!!!!! Here’s a rundown of some of the things you may notice are different now: We’ve moved onto the Zooniverse Project Builder. This means that it’s much easier for us to change out image sets as necessary (e.g. adding on objects that receive Gaia parallaxes), and it’s easier for us to update the project otherwise. Instead of using SDSS and DSS2, we’re using PanSTARRS and Skymapper for our images at visible wavelengths. These surveys have higher spatial resolution and pro ..read more

Our New Paper: “Peter Pan Disks”!

We recently had another article accepted for publication in the Astrophysical Journal! A pre-print is now available on arXiv. This one presents four new identifications of long-lived accretion disks around M dwarfs (like the object in our second paper), presents new data on the first one we identified, and uses these data to define a class of “Peter Pan” disk. In 1904, J.M. Barrie wrote the play (and book) “Peter Pan, or The Boy Who Wouldn’t Grow Up,” about a boy Peter Pan who stayed the same age forever. It was later adapted into a stage musical and a Disney animated movie. Here, we use the t ..read more

We have a database! Thanks to a grant from the Space Telescope Science Institute, much of the Disk Detective science product is now available through the MAST archive. What you’ll find there: Information on the classification data of individual objects from Disk Detective; Additional review information (literature review; more detailed examination) provided by members of the Disk Detective team; Cross-matches with Gaia, Pan-STARRS DR1, the TESS Input Catalog, and the APASS DR9 Catalog; Basic blackbody model SED fits to the observed data, with best-fit stellar effective temperature, disk temper ..read more
