A magnetic field study of two fast-rotating, radio bright M dwarfs. StKM 1-1262 and V374 Peg

S. Bellotti, P. I. Cristofari, J. R. Callingham +8

Radio observations at low frequencies are sensitive to the magnetic activity of stars and the plasma environment surrounding them. The accurate interpretation of the processes unde…

Can scallop-shell stars trap dust in their magnetic fields?

Hannah Sanderson, Moira Jardine, Andrew Collier Cameron +2

One of the puzzles to have emerged from the Kepler and TESS missions is the existence of unexplained dips in the lightcurves of a small fraction of rapidly-rotating M dwarfs in you…

Linking chromospheric activity and magnetic field properties for late-type dwarf stars

E. L. Brown, S. V. Jeffers, S. C. Marsden +9

Spectropolarimetric data allow for simultaneous monitoring of stellar chromospheric activity and the surface-averaged longitudinal magnetic field, $B_l…

MOVES V. Modelling star-planet magnetic interactions of HD 189733

A. Strugarek, R. Fares, V. Bourrier +10

Magnetic interactions between stars and close-in planets may lead to a detectable signal on the stellar disk. HD 189733 is one of the key exosystems thought to harbor magnetic inte…

The crucial role of surface magnetic fields for stellar dynamos: Epsilon Eridani, 61 Cygni A, and the Sun

S. V. Jeffers, R. H. Cameron, S. C. Marsden +9

Cool main-sequence stars, such as the Sun, have magnetic fields which are generated by an internal dynamo mechanism. In the Sun, the dynamo mechanism produces a balance between the…

A hot Jupiter around the very active weak-line T Tauri star TAP 26

L. Yu, J. -F. Donati, E. M. Hébrard +17

We report the results of an extended spectropolarimetric and photometric monitoring of the weak-line T Tauri star TAP 26, carried out within the MaTYSSE programme with the ESPaDOnS…

The shocking transit of WASP-12b: Modelling the observed early ingress in the near ultraviolet

J. Llama, K. Wood, M. Jardine +4

Near ultraviolet observations of WASP-12b have revealed an early ingress compared to the optical transit lightcurve. This has been interpreted as due to the presence of a magnetosp…

Ionisation in atmospheres of Brown Dwarfs and extrasolar planets I The role of electron avalanche

Ch. Helling, M. Jardine, S. Witte +1

Brown Dwarf and extrasolar planet atmospheres form clouds which strongly influence the local chemistry and physics. These clouds are globally neutral obeying dust-gas charge equili…

Why are accreting T Tauri stars observed to be less luminous in X-rays than non-accretors?

S. G. Gregory, K. Wood, M. Jardine

Accreting T Tauri stars are observed to be less luminous in X-rays than non-accretors, an effect that has been detected in various star forming regions. To explain this we have com…
