Discover of the "missing" mode in HR 1217 by the Whole Earth Telescope

D. W. Kurtz, S. D. Kawaler, R. L. Riddle et al.

HR 1217 is a prototypical rapidly oscillating Ap star that has presented a test to the theory of nonradial stellar pulsation. Prior observations showed a clear pattern of five mode…

Constraining the Matter Power Spectrum Normalization using the SDSS/RASS and REFLEX Cluster surveys

Pedro T. P. Viana, Robert C. Nichol, Andrew R. Liddle

We describe a new approach to constrain the amplitude of the power spectrum of matter perturbations in the Universe, parametrized by sigma_8 as a function of the matter density Ome…

Modified Median Statistics and Type Ia Supernova Data

P. P. Avelino, C. J. A. P. Martins, P. Pinto

The median statistic has recently been discussed by Gott \textit{et al.} as a more reliable alternative to the standard likelihood analysis, in the sense of requiring fewer a…

Asteroseismic Inference for Solar-Type Stars

M. J. P. F. G. Monteiro, J. Christensen-Dalsgaard, M. J. Thompson

The oscillation spectra of solar-type stars may in the not-too- distant future be used to constrain certain properties of the stars. The CD diagram of large versus small frequency…

Atomic T Tauri disk winds heated by ambipolar diffusion II- Observational tests

Paulo J. V. Garcia, Sylvie Cabrit, Jonathan Ferreira +1

Thermal and ionization structures of self-similar, magnetically-driven disk winds obtained in a companion paper \cite{Garcia2001a} are used to compute a series of jet synthetic obs…

Atomic T Tauri disk winds heated by ambipolar diffusion I- Thermal structure

Paulo J. V. Garcia, Jonathan Ferreira, Sylvie Cabrit +1

Motivated by recent subarcsecond resolution observations of jets from T Tauri stars, we extend the work of \citep{Safier93a, Safier93b} by computing the thermal and ionization stru…
