Evolution of gas and dust incircumstellar environments: from protoplanetary discs to the formation of planets
Understanding the evolution of gas and dust in circumstellar discs is a major topic in present day astronomy, linked to one of the most interesting challenges: understanding the formation of planets. Circumstellar discs can be found around stars at different ages, and circumstellar matter follows an evolutionary path that links the different kinds of discs […]
A search for low-mass objects in young star-forming regions
The object of this thesis is find new low-mass objects in Taurus in order to get new insights on its mass function. The investigated area in this work is located 5 deg north of the main clouds and covers around 25 sq:deg. Thus, we also contribute to answer the question whether the low-mass objects have […]
