Characterization of the atmosphere of the exoplanet Wasp-107b using SYSREM and cross-correlation

Autor: Rubio Fernández, Hugo

This project consists on the characterisation of the atmosphere of the exoplanet Wasp-107b, by observing the existence (or absence) of 4 different molecules: H20, CO2, CO and CH4. To achieve this we use 2 algorithms: - SYSREM, which eliminates the un

Deep learning for neutrino detection using Transformer architecture.

Autor: Alin, Hans

Detecting neutrinos, especially ultra-high-energy (UHE) neutrinos, is inherently challenging. Highly sensitive detection devices are required to effectively capture these rare particles, which often results in significant noise in the data. This proj

Oscillations in a complex sunspot: From theory to data

Autor: Kranenbarg, Femke

Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneou

We present an empirical model of age-dependent photospheric lithium depletion, calibrated using a large, homogeneously-analysed sample of 6200 stars in 52 open clusters, with ages from 2--6000 Myr and $-0.3

Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the process of the impact ejecta evolving into a tail has never been direct
