On shared indefinite expressions in coordinative structures

The paper shows that shared indefinite expressions in coordinative constructions may differ with respect to their referential properties. This is due to their being either in a focused or in a nonfocused shared constituent. Their different information-structural status follows from Rooth's theory on focus interpretation. Thus it follows that focused shared constitutents must be beyond the actual coordination and that coordinative constructions with unfocused shared constituents can be represented as ellipsis. In a focused shared constituent indefinite expressions may have a specific and an non specific unique reading as well as an non specific distributive one. For the latter we outline the idea that subjects and objects in the actual coordination form a pair of sets to which a distributing operator is attached. The set formation is further supported by plural pronouns referring to the respective set and by plural verb agreement in subsequent expressions

LBV (Candidate) Nebulae: Bipolarity and Outflows

The most massive evolved stars (above 50 M_sun) undergo a phase of extreme mass loss in which their evolution is reversed from a redward to a blueward motion in the HRD. In this phase the stars are known as Luminous Blue Variables (LBVs) and they are located in the HRD close to the Humphreys-Davidson limit. It is far from understood what causes the strong mass loss or what triggers the so-called giant eruptions, active events in which in a short time a large amount of mass is ejected. Here I will present results from a larger project devoted to better understand LBVs through studying the LBV nebulae. These nebulae are formed as a consequence of the strong mass loss. The analysis concentrates on the morphology and kinematics of these nebulae. Of special concern was the frequently observed bipolar nature of the LBV nebulae. Bipolarity seems to be a general feature and strongly constrains models of the LBV phase and especially of the formation of the nebulae. In addition we found outflows from LBV nebulae, the first evidence for ongoing instabilities in the nebulae.Comment: 2 pages, to appear in : K.A. van der Hucht, A. Herrero & C.

Determination of the b-quark mass and nonperturbative parameters in semileptonic and radiative penguin decays at BABAR

Knowing the mass of the b-quark is essential to the study of the structure and decays of B mesons as well as to future tests of the Higgs mechanism of mass generation. We present recent preliminary measurements of the b-quark mass and related nonperturbative parameters from moments of kinematic distributions in charmed and charmless semileptonic and radiative penguin B decays. Their determination from charmless semileptonic B decays is the first measurement in this mode. The data were collected by the BABAR detector at the PEP-II asymmetric-energy e+e- -collider at the Stanford Linear Accelerator Center at a center-of-momentum energy of 10.58 GeV.Comment: Contributed to the proceedings of the 12th International Conference on Hadron Spectroscopy (Hadron 07), Frascati, Italy, 8-13 Oct 2007. 7pp, 4 figures. v2: Replaced Fig. 3 (b) with correct versio

Sluicing phenomena

The paper shows that in various sluicing types, the wh-phrase in the sluicing sentence as well as its relatum in the antecedent clause must be F-marked, and it explains this observation with Schwarzschild's (1999) and Merchant's (1999) focus theory. According to the semantics of the wh-phrase, it will argue that the relatum of the wh-phrase is an indefinite expression that must allow a specific interpretation. Following Heusinger (1997, 2000), specificity will be defined as an anchoring relation between the discourse referent introduced by the indefinite expression and a discourse given item. Because specific indefinite expressions are always novel, contexts like the scope of definite DPs, the scope of thematic matrix predicates, and the scope of downward-monotonic quantifiers which all exhibit non-novel indefinites do not allow sluicing
