Long-term X-ray variability of the multiple-planet host L 98-59: Hints of an activity cycle

I. Pillitteri, S. Bellotti, S. Benatti +7

High-energy irradiation in X-rays and UV (XUV) can transform the planetary atmospheres through photoevaporation and photochemistry. This is more crucial for M stars, whose habitabl…

Empirical prediction of plasma emission measure distributions and X-EUV spectra of late-type stars

Antonio Maggio, Ignazio Pillitteri, Jorge Sanz-Forcada +1

High-energy emission spectra from the outer atmospheres of late-type stars represent an important feature of the stellar activity in several contexts, such as the photoevaporation…

A scaling relationship for non-thermal radio emission from ordered magnetospheres - II. Investigating the efficiency of relativistic electron production in magnetospheres of BA-type stars

P. Leto, S. Owocki, C. Trigilio +19

Magnetic BA stars host dipole-like magnetospheres. When detected as radio sources, their luminosities correlate with the magnetic field and rotation. Rotation is crucial because th…

XUV irradiation of young planetary atmospheres. Results from a joint XMM-Newton and HST observation of HIP67522

A. Maggio, I. Pillitteri, C. Argiroffi +3

The evaporation and the chemistry of the atmospheres of warm and hot planets are strongly determined by the high-energy irradiation they receive from their parent stars. This is mo…

The enigmatic dance of the HD 189733A system: Does the planet accrete onto the star?

Salvatore Colombo, Ignazio Pillitteri, Antonino Petralia +2

Several studies suggest that the emission properties of a star can be affected by its interaction with a nearby planet. However, the actual observability of these effects remains a…

XUV emission of the young planet-hosting star V1298\,Tau from coordinated observations with XMM-Newton and HST

A. Maggio, I. Pillitteri, C. Argiroffi +16

Atmospheric mass loss plays a major role in the evolution of exoplanets. This process is driven by the stellar high-energy irradiation, especially in the first hundreds of millions…
