Colours and magnitudes of the central star of NGC 650 and its two companions have been obtained from HST images. The spectral types of the companions, which have been deduced from the colours, suggest a probable distance to the companions of between 5 and 6 kpc. Using the spectral and photometric characteristics of the central star, which are very similar to the very well studied PN PG 1159, we...

We present the results of a survey for stellar and substellar companions to 82 young stars in the nearby OB association Upper Scorpius. This survey used nonredundant aperture mask interferometry to achieve typical contrast limits of K 5Y6 at the diffraction limit, revealing 12 new binary companions that lay below the detection limits of traditional high-resolution imaging; we also summarize a c...

We present an analysis of 11 yr of precision radial velocity measurements of 76 nearby solar-type stars from the Lick radial velocity survey. For each star, we report on variability, periodicity, and long-term velocity trends. Our sample of stars contains eight known companions with mass less than 8 (M p sin i) Jupiter masses six of which were discovered at Lick. For the remaining stars, we pla...

Assuming with Boškoviƒ (1997), who adopts Split I, that sentential adverbs are TP-adjoined, Stjepanoviƒ suggests SC Vs move to T. She also suggests the movement is optional due to Pravilno odgovara Mileni, where pravilno is ambiguous (it can have sentential reading). As in English, there is a V/aux contrast in SC: in contrast to Vs, auxiliaries can precede sentential adverbs (clitics are given ...

khunaji and his companions get influence from fakhr al-din razi and classified quantified propositions into two kinds: factual and external. abhari added the third kind which was named mental. tusi and his companions refuted khunaji’s viewpoint. analysis and explanation of the historical development of classification of predicative proposition into factual, external and mental is the problem of...
