The point spread function in Lucky Imaging and variations in seeing on short timescales

Autor: Craig D. Mackay, John E. Baldwin, Peter J. Warner

Publikováno v: Astronomy & Astrophysics. 480:589-597

Aims. We investigate the properties of astronomical images made by combining the best images selected from a sequence of shortexposure frames (Lucky Imaging); we assess the match between modelling and observation and discover what variations in seein

A final non-redundant catalogue for the 7C 151-MHz survey

Autor: John E. Baldwin, S. E. G. Hales, J. M. Riley, E. M. Waldram, Peter J. Warner

Publikováno v: Monthly Notices of the Royal Astronomical Society. 382:1639-1642

We present a final unified catalogue for the 7C survey at 151 MHz with resolution 70 × 70 cosec(δ) arcsec 2 . This has been constructed by amalgamating the existing catalogues derived from individual fields imaged at this resolution and eliminating

Influence of herbivores on a perennial plant: variation with life history stage and herbivore species

Autor: Hall J. Cushman, Peter J. Warner

Publikováno v: Oecologia. 132:77-85

Herbivores have diverse impacts on their host plants, potentially altering survival, growth, fecundity, and other aspects of plant performance. Especially for longer-lived plant species, the effects of a single herbivore species can vary markedly thr

New views of Betelgeuse: multi-wavelength surface imaging and implications for models of hotspot generation

Autor: Peter J. Warner, Christopher A. Haniff, Richard Wilson, Craig D. Mackay, Peter R. Lawson, Roger C. Boysen, Donald M. A. Wilson, John Young, Debbie Pearson, John E. Baldwin, John H. Rogers, D. St.-Jacques

Publikováno v: Monthly Notices of the Royal Astronomical Society. 315:635-645

ABSTRA C T We report contemporaneous multi-wavelength interferometric imaging of the red supergiant star Betelgeuse (a Orionis), using the Cambridge Optical Aperture Synthesis Telescope (COAST) and the William Herschel Telescope (WHT), at wavelengths

Measurements of the changes in angular diameter of Mira variables with pulsation phase

Autor: John E. Baldwin, John H. Rogers, Donald M. A. Wilson, D. St-Jacques, John Young, Peter J. Warner, Roger C. Boysen, Christopher A. Haniff, Debbie Pearson

Publikováno v: Symposium - International Astronomical Union. 191:145-150

We report the direct detection of cyclic diameter variations in the Mira variable χ Cygni. Interferometric observations made between 1997 July and 1998 September, using the Cambridge Optical Aperture Synthesis Telescope (COAST) indicate periodic cha
