Searching for Faint Companions with the TRIDENT Differential Simultaneous Imaging Camera
C. Marois, D. Nadeau, R. Doyon +2
We present the first results obtained at CFHT with the TRIDENT infrared camera, dedicated to the detection of faint companions close to bright nearby stars. Its main feature is the…
Differential Simultaneous Imaging and Faint Companions: TRIDENT First Results from CFHT
C. Marois, D. Nadeau, R. Doyon +2
We present the first results obtained at CFHT with the TRIDENT infrared camera, dedicated to the detection of faint companions close to bright nearby stars. Its main feature is the…
The Impossibility of Pseudo-Telepathy Without Quantum Entanglement
Viktor Galliard, Stefan Wolf, Alain Tapp
Imagine that Alice and Bob, unable to communicate, are both given a 16-bit string such that the strings are either equal, or they differ in exactly 8 positions. Both parties are th…
Relationship between dynamical heterogeneities and stretched exponential relaxation
S. I. Simdyankin, Normand Mousseau
We identify the dynamical heterogeneities as an essential prerequisite for stretched exponential relaxation in dynamically frustrated systems. This heterogeneity takes the form of…
Of Variability, or its Absence, in HgMn Stars
S. Turcotte, O. Richard
Current models and observations of variability in HgMn stars disagree. We present here the models that argue for pulsating HgMn stars with properties similar to those of Slowly Pul…
Discovery of A New Class of Pulsating Stars: Gravity-mode Pulsators among Subdwarf B Stars
E. M. Green, G. Fontaine, M. D. Reed +15
During the course of an ongoing CCD monitoring program to investigate low-level light variations in subdwarf B (sdB) stars, we have serendipitously discovered a new class of low am…
