Implications for the formation of Oort cloud-like structures and interstellar comets in dense environments
Santiago Torres
Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems. The solar system, with…
A homogeneous three-dimensional view of Molecular Cloud kinematics out to 2.5 kpc. Using Young Stellar Objects and Open Clusters as complementary tracers
Xabier Pérez-Couto, Santiago Torres, Nuria Miret-Roig +4
Understanding the large-scale dynamics of molecular clouds (MCs) is crucial for constraining the processes that govern star formation and the structure and evolution of the Galaxy.…
The Future of Evolved Planetary Systems
Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19
Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…
A Kinematic History of Stellar Encounters with Beta Pictoris
Jose Luis Gragera-Más, Santiago Torres, Alexander James Mustill +1
Beta Pictoris is an A-type star hosting a complex planetary system with two massive gas giants and a prominent debris disk. Variable absorption lines in its stellar spectrum have b…
Combining REBOUND and MESA: Dynamical Evolution of Planets Orbiting Interacting Binaries
Zepei Xing, Santiago Torres, Ylva Götberg +3
Although planets have been found orbiting binary systems, whether they can survive binary interactions is debated. While the tightest-orbit binaries should host the most dynamicall…
Redshifted Sodium Transient near Exoplanet Transit
Apurva V. Oza, Julia V. Seidel, H. Jens Hoeijmakers +21
Neutral sodium (Na I) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine…
