Magnetic topologies of young suns: The weak-line T Tauri stars TWA 6 and TWA 8A
C. A. Hill, C. P. Folsom, J. -F. Donati +5
We present a spectropolarimetric study of two weak-line T Tauri stars (wTTSs), TWA 6 and TWA 8A, as part of the MaTYSSE (Magnetic Topologies of Young Stars and the Survival of clos…
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 long-term evolution of stellar activity
Scott G. Gregory
I review the evolution of low-mass stars with outer convective zones over timescales of millions-to-billions of years, from the pre-main sequence to solar-age, ~4.6 Gyr (Bahcall et…
The multipolar magnetic fields of accreting pre-main-sequence stars: B at the inner disk, B along the accretion flow, and B at the accretion shock
Scott G. Gregory, Jean-François Donati, Gaitee A. J. Hussain
Zeeman-Doppler imaging studies have revealed the complexity of the large-scale magnetic fields of accreting pre-main-sequence stars. All have multipolar magnetic fields with the oc…
The coronal evolution of pre-main-sequence stars
Scott G. Gregory, Fred C. Adams, Claire L. Davies
The bulk of X-ray emission from pre-main-sequence (PMS) stars is coronal in origin. We demonstrate herein that stars on Henyey tracks in the Hertzsprung-Russell diagram have lower…
A Model for (Quasi-)Periodic Multi-wavelength Photometric Variability in Young Stellar Objects
Aurora Y. Kesseli, Maya A. Petkova, Kenneth Wood +7
We present radiation transfer models of rotating young stellar objects (YSOs) with hotspots in their atmospheres, inner disk warps and other 3-D effects in the nearby circumstellar…
