RT info:eu-repo/semantics/masterThesis T1 Seguimiento de las trayectorias de los objetos de masa planetaria más fríos y cercanos A1 Villafañe Calvo, Juan A2 Máster Universitario en Astrofísica AB This master’s thesis focuses on the study of trajectories of Y dwarfs. These objects arethe coldest and smallest stellar bodies not considered planets. A considerable amountof the properties and characteristics of these Y dwarfs are still unknown. This is causedby the fact that they barely emit visible light and they are also very faint in the infrared.As an example, one of the stars in this work, WISE J0855-0714, is the eighth closest knownstellar object to the Sun and it was not known until 2014.
