Detection of circular polarization in light scattered from photosynthetic microbes
William B. Sparks, James Hough, Thomas A. Germer +9
The identification of a universal biosignature that could be sensed remotely is critical to the prospects for success in the search for life elsewhere in the universe. A candidate…
A new spectroscopic and interferometric study of the young stellar object V645 Cyg
A. S. Miroshnichenko, K. -H. Hofmann, D. Schertl +14
We present the results of high-resolution optical spectroscopy, low-resolution near-IR spectroscopy and near-infrared speckle interferometry of the massive young stellar object can…
Magnetospheric accretion on the T Tauri star BP Tauri
J. F. Donati, M. M. Jardine, S. G. Gregory +15
From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star BP Tau. Circular polarisati…
Rotation and Macroturbulence in Metal-poor Field Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David F. Gray, David Yong +4
We report the results for rotational velocities, Vrot sin i, and macroturbulence dispersion, zeta(RT), for 12 metal-poor field red giant branch stars and 7 metal-poor field red hor…
The surprising magnetic topology of tauSco: fossil remnant or dynamo output?
JF Donati, ID Howarth, MM Jardine +9
We report the discovery of a medium-strength (~0.5kG) magnetic field on the young, massive star tauSco (B0.2V), which becomes the third-hottest magnetic star known. Circularly pola…
Polarimetry of binary stars
N. Manset
Astronomical polarimetry is a powerful technique that can provide physical information sometimes difficult or impossible to obtain by any other type of observation. Almost every cl…
