Fundamental Limit on “Interaction Free” Measurements

In a highly influential recent paper by Elitzur and Vaidman, it was pointed out that the presence of an object (often called a “bomb”) can often be discerned without it absorbing even a single photon. This “interaction free measurement” scheme and later improvements on it2–5 have received a lot of attention, both in the popular press as well as in serious scientific journals2–5,7. In this paper...

Cross - correlation radial velocity measurements ofchromospherically

We present observational radial velocity curves for 12 chromospherically active binary systems and individual measurements for a further 5 systems. These binaries are Six of our target binaries do not agree with published ephemerides or orbital parameters. We also present a rigourous derivation of the resolution limit for binary star cross-correlation radial velocities. Using synthetic spectral...

Radial velocity measurements of white dwarfs

We present 594 radial velocity measurements for 71 white dwarfs obtained during our search for binary white dwarfs and not reported elsewhere. We identify three excellent candidate binaries, which require further observations to confirm our preliminary estimates for their orbital periods, and one other good candidate. We investigate whether our data support the existence of a population of sing...

A Goldilocks principle for modelling radial velocity noise

The Doppler measurements of stars are diluted and distorted by stellar activity noise. Different choices of noise models and statistical methods have led to much controversy in the confirmation of exoplanet candidates obtained through analysing radial velocity data. To quantify the limitation of various models and methods, we compare different noise models and signal detection criteria for vari...
