Idiosyncratic Astrophysics

Astrophysics.

Using the oscillation frequencies of α Cen A recently discovered by Bouchy & Carrier (2001, 2002), the available astrometric, photometric and spectroscopic data, we tried to improve the calibration of the visual binary system α Cen. With the revisited masses of Pour-baix et al. (2002) we do not succeed to obtain a solution satisfying all the seismic observational constraints. Relaxing the const...

ASTROPHYSICS The NASA Astrophysics Data System : Overview

The NASA Astrophysics Data System Abstract Service has become a key component of astronomical research. It provides bibliographic information daily, or near daily, to a majority of astronomical researchers worldwide. We describe the history of the development of the system and its current status. Urania (Boyce 1996), and the ADS role in the emerging electronic astronomical data environment are ...

AGGREGATE IDIOSYNCRATIC VOLATILITY Geert

We examine aggregate idiosyncratic volatility in 23 developed equity markets, measured using various methodologies, and we find no evidence of upward trends. Instead, idiosyncratic volatility appears to be well described by a stationary autoregressive process that occasionally switches into a higher-variance regime that has relatively short duration. We also document that idiosyncratic volatili...

Ambiguity and Idiosyncratic Interpretation

This paper discusses logics whose premisses and/or conclusions can contain ambiguous material. Two different kinds of applications are sketched for these logics. First, the paper discusses how logics with ambiguous expressions can shed light on the way in which human hearers or readers understand certain 'paradoxical' logical arguments, in which crucial use is made of ambiguous material. Second...
