| Description: | Brown dwarfs (BD) are substellar objects that, due to their low mass, are unable to maintain hydrostatic equilibrium and eventually cool down and become dimmer. These objects belong to the ultra-cool dwarfs group, and because of their low luminosity are difficult to detect. Yet, starting in the 90s, many infrared (IR) surveys have proven to be prolific in terms of BDs detection, and one of them is the Wide-field Infrared Survey Explorer (WISE). On the basis of this survey, the unWISE catalog, containing around 2,200 M objects, has recently been developed. Its main advantage is that it is deeper than other IR surveys, thus allowing the detection of faint sources that might have been overlooked. This project aims at searching for new BDs candidates that haven’t been detected yet, employing the unWISE catalog as the main source of data. The project involved many types of activities, from understanding the physics of these special objects to data analysis and programming. Starting with an initial population of two billions of sources, a BD candidate list of 16 objects was obtained at the end of the project. Further analyses and follow-up observations would be required to reach a definitive conclusion regarding their nature. |
