Measuring-analytical complex for investigation of local C-V- characteristics of semiconductor barrier structures on the basis of AFM

Разработан автоматизированный измерительный комплекс для локального исследования вольт-фарадных характеристик полупроводниковых структур на основе зондовой системы атомно-силового микроскопа.Automated measuring complex for local research of capacitor-voltage characteristics of semiconductor structures based on the probe system of an atomic force microscope has been developed.Работа выполнена при финансовой поддержке РФФИ (грант 16-32-00342) с использованием оборудования Регионального центра зондовой микроскопии коллективного пользования (РЦЗМкп) при ФГБОУ ВО «РГРТУ» (ckp.rsreu.ru) в НОЦ неупорядоченных и наноструктурированных материалов и устройств на их основе (ННМУ)

A Search for Pulsating, Mass-Accreting Components in Algol-Type Eclipsing Binaries

We present a status report on the search for pulsations in primary componants of Algols systems (oEA stars). Analysis of 21 systems with A0-F2 spectral type primaries revealed pulsations in two systems suggesting that of the order of ten persent of Algols primaries in this range are actually pulsators

Spectroscopy and Photometry of MWC 137

MWC 137 is an object with a strong emission-line spectrum associated with an 1'-size H Imall> region Sharpless 266. It was included in a catalog of planetary nebulae in 1967, in the first list of objects with the B[e] phenomenon in 1976, and in a list of Herbig Ae/Be stars in 1984. A recent analysis of the stellar and nebular spectra of MWC 137 by several authors suggested that it is most likely a B[e] supergiant located at a distance 4-6 kpc away from the Sun. No high-resolution spectra of the object have been published so far. We present the results of our analysis of high-resolution optical spectra of MWC 137 obtained in 2004-2016 and UBVRI photometry
