- Searching for star-planet magnetic interaction in CoRoT observations. Lanza, A. // Astrophysics & Space Science;Oct2011, Vol. 336 Issue 2, p303
Close-in massive planets interact with their host stars through tidal and magnetic mechanisms. In this paper, we review circumstantial evidence for star-planet interaction as revealed by the photospheric magnetic activity in some of the CoRoT planet-hosting stars, notably CoRoT-2, 4, and 6. The...
- Star's magnetic somersaults down to hot Jupiter. // New Scientist;7/11/2009, Vol. 203 Issue 2716, p16
The article discusses research on the cause of the magnetic flips to be observed in the star Tau Bo�tis, the first one to be seen in a star other than the sun. To deduce the strength and orientation of the star's magnetic field, Rim Fares at the Paul Sabatier University in France and...
- Multiwavelength flux variations induced by stellar magnetic activity: effects on planetary transits. Ballerini, P.; Micela, G.; Lanza, A. F.; Pagano, I. // Astronomy & Astrophysics / Astronomie et Astrophysique;Mar2012, Vol. 539, p1
Stellar magnetic activity is a source of noise in the study of the transits of extrasolar planets. It induces flux variations that significantly affect the transit depth determination and the derivations of planetary and stellar parameters. Furthermore, the colour dependence of stellar activity...
- Formation of stars and planets: the role of magnetic fields. Salmeron, R. // Astrophysics & Space Science;Sep2011, Vol. 335 Issue 2, p353
Star formation is thought to be triggered by gravitational collapse of the dense cores of molecular clouds. Angular momentum conservation during the collapse results in the progressive increase of the centrifugal force, which eventually halts the inflow of material and leads to the development...
- Energy flux determines magnetic field strength of planets and stars. Christensen, Ulrich R.; Holzwarth, Volkmar; Reiners, Ansgar // Nature;1/8/2009, Vol. 457 Issue 7226, p167
The magnetic fields of Earth and Jupiter, along with those of rapidly rotating, low-mass stars, are generated by convection-driven dynamos that may operate similarly (the slowly rotating Sun generates its field through a different dynamo mechanism). The field strengths of planets and stars vary...
