Hydrodynamic simulations of convection and nucleosynthesis in the late phases of massive stars to constrain and guide stellar evolution theory (2023)
Thesis

The present knowledge of stellar evolution is still limited today by large uncertainties that derive from the complex multi-dimensional processes occurring in stars. Among them, the turbulent motions of the stellar fluid control the size and evolutio...

Optical and Infrared Counterparts of the X-Ray Sources Detected in the Chandra Cygnus OB2 Legacy Survey (2023)
Journal Article

The young massive OB association Cygnus OB2, in the Cygnus X complex, is the closest (∼1400 pc) star-forming region to the Sun hosting thousands of young low-mass stars and up to 1000 OB stars, among which are some of the most massive stars known in...

A new method for spatially resolving the turbulence driving mixture in the ISM with application to the Small Magellanic Cloud (2023)
Journal Article

Turbulence plays a crucial role in shaping the structure of the interstellar medium. The ratio of the three-dimensional density contrast ($\sigma _{\rho /\rho _0}$) to the turbulent sonic Mach number ($\mathcal {M}$) of an isothermal, compressible ga...

Fundamental parameters of very low mass stars in eclipsing binary star systems observed with the CHEOPS satellite (2023)
Thesis

Observations of low-mass stars have frequently shown unexpectedly large stellar radii when compared to the predictions from theoretical stellar structure models. This “radius inflation” problem may have consequences not just for stellar science but a...

Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS: TOI-615b, TOI-622b, and TOI-2641b (2023)
Journal Article

While the sample of confirmed exoplanets continues to grow, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investigate the planet properties and formation pathways over a wide range of stel...

Deciphering the atmospheric properties of hot gas giant exoplanets via ground-based transmission spectroscopy (2023)
Thesis

Transiting hot gas giant exoplanets are great targets for atmospheric investigations due to their extended atmospheres and their strong obscuring effect on the observed starlight when they pass in front of their host star. Transmission spectroscopy c... Read More about Deciphering the atmospheric properties of hot gas giant exoplanets via ground-based transmission spectroscopy.

Fundamental effective temperature measurements for eclipsing binary stars – IV. Selection of new benchmark stars and first results for HD 22064 (2023)
Journal Article

I describe the selection and initial characterization of 20 eclipsing binary stars that are suitable for calibration and testing of stellar models and data analysis algorithms used by the PLATO mission and spectroscopic surveys. The binary stars sele... Read More about Fundamental effective temperature measurements for eclipsing binary stars – IV. Selection of new benchmark stars and first results for HD 22064.

Power-2 limb-darkening coefficients for the uvby, UBVRIJHK, SDSS ugriz, Gaia, Kepler, TESS, and CHEOPS photometric systems II. PHOENIX spherically symmetric stellar atmosphere models. (2023)
Journal Article

Context. The phenomenon of limb-darkening is relevant to many topics in astrophysics, including the analysis of light curves of eclipsing binaries, optical interferometry, measurement of stellar diameters, line profiles of rotating stars, gravitation...

Validation of TOI-1221 b: A Warm Sub-Neptune Exhibiting Transit Timing Variations around a Sun-like Star (2023)
Journal Article

We present a validation of a long-period (91.68278 (+0.00032)(-0.00041) days) transiting sub-Neptune planet, TOI-1221 b (TIC 349095149.01), around a Sun-like (m(V)= 10.5) star. This is one of the few known exoplanets with a period >50 days, and belon... Read More about Validation of TOI-1221 b: A Warm Sub-Neptune Exhibiting Transit Timing Variations around a Sun-like Star.
