Studies of solar white-light flares and small-scale magnetic structures observed in the near infrared
… flares and small magnetic structures, such as faculae and pores, are presented in this dissertation. The investigations focus on near-infrared observations at 1.56 um, which are good proxy of the deepest layer of the solar photosphere. I made fundamental contributions in two areas of near …

Unearth: Revealing the Effects of Stellar Activity on Exoplanet Host Stars
… goal. For inactive stars like the Sun, plage/faculae are thought to be the major contributors to this noise, but its effects have so far proven difficult to trace.<br/><br/>In this thesis, I investigate the effect activity has on stellar spectra, using HARPS data of the well observed K1 V star …

Effects of starspots activity on optical and near infrared observations of planetary transits
… inhomogeneities, such as starspots or bright faculae, on star disc have an intrinsic dependence on wavelength and thus on the stellar colours. The colour dependence of stellar activity may significantly influence the characterization of planetary atmospheres since it produces stellar flux …

PROPERTIES AND CORRELATION OF FLARES AND CORONAL MASS EJECTIONS AND THEIR POSSIBLE RELEVANCE ON THE SOUTHERN NIGHT SKY BACKGROUND : A STATISTICAL STUDY
… to localized magnetic fields: sunspots, faculae, filaments, active regions, bright points, coronal holes, etc. The occurrence of these phenomena is variable, depending on the so-called activity cycle, characterized by a period of 11 years. Moreover, in some situations, the magnetic field …
