We present spherically symmetric and plane-parallel photoionization models of NGC 346, an H II region in the Small Magellanic Cloud. The models are based on...
Photoionized Herbig-Haro Objects in the Orion Nebula through Deep High Spectral Resolution Spectroscopy. II. HH 204
We analyze the physical conditions, chemical composition, and other properties of the photoionized Herbig-Haro (HH) object HH 204 through Very Large Telescope...
Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy - I. HH 529 II and III
We present the analysis of physical conditions, chemical composition, and kinematic properties of two bow shocks - HH 529 II and HH 529 III - of the fully...
Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy - III. HH 514
We analyse the physical conditions and chemical composition of the photoionized Herbig-Haro object HH 514, which emerges from the protoplanetary disc (proplyd)...
Photolytic Decomposition of Hydrogenated C70: C70H38 and C70D38
The hydrogenated C70 fullerenes C70H38 and C70D38 have been photolyzed at 245nm under Ar or He flow. The photolysis rate constant have been measured: k = 1...
Photometric Amplitude Distribution of Stellar Rotation of KOIs—Indication for Spin-Orbit Alignment of Cool Stars and High Obliquity for Hot Stars
The observed amplitude of the rotational photometric modulation of a star with spots should depend on the inclination of its rotational axis relative to our...
Photometric and astrometric analysis of a mutual event between the Uranian satellites Miranda and Oberon
Observations of the predicted occultation between the satellites Miranda and Oberon were performed on 2007 July 30. Data analysis reveals that the predicted...
Photometric and colorimetric studies of target objects using small and medium-size telescopes
We report on follow-up studies of transient events and objects, which have been conducted in recent years using ground-based optical observations. BVRI...
Photometric and spectroscopic study of the burst-like brightening of two Gaia-alerted young stellar objects
Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia...
