The massive white dwarf in the recurrent nova T CrB
We have obtained I, J , H and K band light curves of the recurrent nova T CrB. We find that we can only fit the J band light curve with a Roche-lobe filling secondary star and a dark spot of radius 11–26 (90 per cent confidence) centred at the inner Lagrangian point. We obtain limits to the binary inclination of 38–46 (90 per cent confidence) which when combined with the value for the mass func...

متن کاملThe absorption spectra of immune proteins.
Since the absorption spectra of simple proteins are known to depend on their content of the three aromatic amino acids, tyrosine, tryptophane, and phenylalanine, it was of interest to examine the group of purified immune proteins which weie available in order to determine whether differences in their composition could be found by this method. These proteins, all of which arc associated with imm...
متن کاملAbsorption Spectra of Phytochrome Intermediates
Native phytochrome (124kdalton) was isolated from etiolated seedlings o f Avena sativa L. cv. Pirol (Baywa, Munich). From low temperature spectra (0 °C to — 165°C ) o f phytochrom e samples irradiated either with red or far-red light, spectra o f intermediates were calculated. Both absorption bands o f the phytochrome chromophore were reported. On the pathway P r i V r , native phytochrome does...
متن کاملOptical Absorption Spectra of Bipolarons
The absorption of large bipolarons is investigated using the path-integral method. The response of a bipolaron to an external electromagnetic field is derived in the framework of the memory function approach. The bipolaron optical absorption spectrum consists of a series of relatively narrow peaks. The peculiarities of the bipolaron optical absorption as a function of the frequency of the elect...
