... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

... Future seminars . ... Long -term evolution of 27 days signal in solar activity and terrestrial magnetic indices - common features and differences ". ... The 27-day signal created by the solar rotation is reflected by the 27-day geomagnetic signal.

Properties of the Solar Eruptive Event of 19 October 2001, 09:40 UT . ... 1) IZMIRAN, Troitsk, Moscow Region, 142190 . ... Basing on IZMIRAN and NIRFI radio observations, we analyze an event which is characterized by sufficiently intense emission in the cm- and dm-ranges under almost total lack of metric bursts. This peculiarity appears to be caused by very slow speed (V~240 km/s) of a coronal mass ejection (CME) recorded in this event with SOHO/LASCO. ... Coronal Mass Ejections . ...

... Pulsars offer a variety of observables for study of interstellar scattering. Observations of scattering of nearby pulsars and intra-day variable quasars point to the existence of a component of the interstellar medium (ISM) which has properties quite different from the more distant, diffuse ISM. ... The time series of electric field emitted by the pulsar is convolved with an impulse-response function due to scattering, when sampled at the observer plane [1]. ... Nearby interstellar scattering. ...
