We report the discovery of the youngest brown dwarf with a disk at 102 pc from the Sun, WISEA~J120037.79-784508.3 (W1200-7845), via the Disk Detective citizen science project. We establish that W1200-7845 is located in the 3.7$\substack{+4.6 \\ -1.4}$ Myr-old $\varepsilon$~Cha association. Its spectral energy distribution (SED) exhibits clear evidence of an infrared (IR) excess, indicative of the presence of a warm circumstellar disk. Modeling this warm disk, we find the data are best fit using…

Gaia-based Isochronal, Kinematic, and Spatial Analysis of the ϵ Cha Association
The precise parallax, proper motion, and photometric measurements contained in Gaia Data Release 2 (DR2) offer the opportunity to reexamine the membership and ages of nearby young moving groups
New low-mass members of Chamaeleon I and ϵ Cha
Aims. The goal of this paper is to increase the membership list of the Chamaeleon star forming region and the Cha moving group, in particular for low-mass stars and substellar objects. We extended

Re-examining the membership and origin of the € Cha association
We present a comprehensive investigation of the Epsilon Chamaeleontis association (Epsilon Cha), one of several young moving groups spread across the southern sky. We re-assess the putative

On the Diversity of the Taurus Transitional Disks: UX Tauri A and LkCa 15
The recently recognized class of transitional disk systems consists of young stars with optically thick outer disks but inner disks which are mostly devoid of small dust grains. Here we introduce a
Probing the Dust and Gas in the Transitional Disk of CS Cha with Spitzer
Here we present the Spitzer IRS spectrum of CS Cha, a member of the ~2 Myr old Chamaeleon star-forming region, which reveals an optically thick circumstellar disk truncated at ~43 AU, the largest
Gaia Data Release 2
The internal analysis of the data shows that the photometric calibrations can reach a precision as low as 2 mmag on individual CCD measurements, and other tests show that systematic effects are present in the data at the 10 mmag level.
Three-dimensional maps of interstellar dust in the Local Arm: using Gaia, 2MASS, and APOGEE-DR14
Context. Gaia data and stellar surveys open the way to the construction of detailed 3D maps of the Galactic interstellar (IS) dust based on the synthesis of star distances and extinctions. Dust maps
A WISE-based search for debris discs amongst M-dwarfs in nearby, young, moving groups
We present a search for debris discs amongst M-dwarf members of nearby, young (5-150 Myr) moving groups (MGs) using infrared (IR) photometry, primarily from the Wide Infrared Survey Explorer (WISE).
