... The spin trail of He II λ4686 also potentially offers a means to conclude the discussion on whether the spin period is 71 s or rather 142 s with two spots contributing to the pulsation. The slope of the simplistic disc ... See full document

... The radial velocities were determined by measuring the wings of the Hβ- and Hγ -emission lines from the 1991 data (1991 April 24 and 25 – the data obtained on the 29th were not added since EX Hya had not ... See full document

... A new indirect method to extract dynamical informa- tion from donor stars in persistent LMXBs was proposed by Steeghs & Casares (2002) (SC02 hereafter). They detected narrow high excitation emission lines from the ... See full document

... To investigate the molecular structure of the stomatal poles that might underpin the observed stiffening, we took an in situ labeling approach to characterize the spatial pattern of cell wall epitopes. Recent work has ... See full document
