Reticence and the upper limit

Developing a Reputation for Reticence∗

A sender who has disclosable information with probability less than one may partially conceal bad news by choosing to withhold information and pooling with uninformed types. The success of this strategy depends on receivers’ beliefs about the probability that the sender has disclosable news. In a dynamic context, informed senders try to cultivate a reputation for reticence either by concealing ...

The Stellar Upper Mass Limit Preserved

This article is based on data gathered with three facilities: the NASA/ESA Hubble Space Telescope (HST), the 6.5 m Magellan Telescopes at Las Campanas Observatory (LCO), and the 2.15-m J. Sahade telescope at Complejo Astronómico El Leoncito (CASLEO). The HST observations are associated with GO program 10602. HST is controlled from the Space Telescope Science Institute, which is operated by the ...

Upper limit of the lifetime of 16B.

The exact location of the drip lines is one of the most stringent tests of nuclear structure models. The predictions for stability of nuclei along the proton drip line can be tested up to very heavy nuclei. Beyond the proton drip line, the large Coulomb barrier and the angular momentum barrier can lead to very long lifetimes for proton-unbound nuclei ~proton radioactivity! @1#. Several of these...
