PHAROS: Panchromatic spectral energy distributions of solar-like stars across evolutionary stages

Viktor Sumida, Raissa Estrela, Eric Mamajek +2

Panchromatic stellar spectral energy distributions (SEDs) provide the wavelength-dependent irradiation fields required for studies of exoplanet atmospheres, photochemistry, atmosph…

Magnetic activity in cool stars: manifestations and relevance to exoplanets

E. Işık, A. Valio, A. Strugarek +10

Understanding stellar magnetic activity is central to exoplanet science in two ways: it sets the dynamic astrospheric boundary condition governing planetary space environments, and…

Star-Planet Interactions: Observational Techniques and Methods

P. Figueira, H. Korhonen, A. Buccino +8

This chapter summarizes the techniques and methods used to study star-planet interaction (SPI) from the observational point of view. SPI can produce a wide range of observational s…

Bimodality in Rotational Modulation of Planet-Hosting Stars

Alexandre Araújo, Adriana Valio

Stellar magnetic activity is governed by the interplay between rotation, convection, and the evolution of surface magnetic structures, yet the role of planetary systems in shaping…

Where does the simplified Stellar Contamination Model fail in Exoplanet Transmission Spectroscopy?

Viktor Y. D. Sumida, Raissa Estrela, Mark Swain +1

Stellar photospheric heterogeneities (e.g., starspots, faculae) distort the stellar spectrum in transit and imprint wavelength-dependent biases on the planet-to-star radius ratio (…

Evaluating Habitability and Biosignature Detection on TOI-700 d: The Role of UV Environment and Atmospheric Pressure

Viktor Y. D. Sumida, Raissa Estrela, Adriana Valio

M dwarfs have long been prime targets in the search for habitable exoplanets, owing to their abundance in the galaxy and the relative ease of detecting Earth-sized worlds within th…
