Radiative levitation: a likely explanation for pulsations in the unique hot O subdwarf star SDSS J160043.6+074802.9
Context. SDSS J160043.6+074802.9 (J1600+0748 for short) is the only hot sdO star for which unambiguous multiperiodic luminosity variations have been reported so far. These rapid variations, with periods in the range from ∼60 s to ∼120 s, are best qualitatively explained in terms of pulsational instabilities, but the exact nature of the driving mechanism has remained a puzzle. Aims. Our primary ...

The purpose of this study was to determine the impact of CYP3A5 expression on inhibitory potency (Ki or IC50 values) of CYP3A inhibitors, using recombinant CYP3A4 and CYP3A5 (rCYP3A4 and rCYP3A5) and CYP3A5 genotyped human liver microsomes (HLMs). IC50 ratios between rCYP3A4 and rCYP3A5 (rCYP3A5/rCYP3A4) of ketoconazole (KTZ) and itraconazole (ITZ) were 8.5 and 8.8 for midazolam (MDZ), 4.7 and ...
متن کاملThe Origin of Helium-Rich Subdwarf O Stars
The origin of helium-rich subdwarf O stars (He-sdO) is still unclear. Significant progress has been made recently in placing them in the Hertzsprung–Russell diagram. However, the question of their progenitors is still unsolved. It is unclear which types of stars evolve into He-sdOs and whether they are formed by all galactic populations. Here I will present results of a radial velocity (RV) sur...
متن کاملRegistration of very time-distant aerial images
In this paper we address the alignment of historical and present-day aerial photographs. Historical images refer to regions bombed during the second world war. In this regions the risk of unexploded bombs is still high, especially where the bombing were more frequent. The alignment is required to fill-in an unexploded bombs risk map. The task is challenging because a lot of features in the hist...
متن کاملA Radio Perspective on Star-Formation in Distant Galaxies
Determination of the epoch dependent star-formation rate of field galaxies is one of the principal goals of modern observational cosmology. Deep radio surveys, sensitive to starbursts out to z ∼ 1-2, may hold the key to understanding the evolution of the starburst phenonemon unhindered by the effects of dust. Using deep, high resolution radio observations of the Hubble Deep Field, we show that ...
