Discovery and characterisation of a new Galactic Planetary Nebula
W. E. Celnik, I. Karachentsev, P. Köchling +9
Planetary nebulae are one of the final stages in the evolution of low and intermediate mass stars. They occur in a variety of shapes. Older and fainter ones are generally more diff…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
More satellites around the nearby spiral galaxy NGC 7331
M. Blauensteiner, I. D. Karachentsev, P. Remmel +5
We report the detection of two dwarf galaxies in a projected distance of ~50 kpc from NGC 7331 and suspect the physical nature of dwarfs of this spiral galaxy.
New Low Surface Brightness Dwarf Galaxies Detected Around Nearby Spirals
I. D. Karachentsev, P. Riepe, T. Zilch +14
We conduct a survey of low surface brightness (LSB) satellite galaxies around the Local Volume massive spirals using long exposures with small amateur telescopes. We identified 27…
Three low surface brightness dwarfs discovered around NGC 4631
Igor D. Karachentsev, Dirk Bautzmann, Fabian Neyer +4
We report the discovery of three low surface brightness companions to the spiral galaxy NGC 4631, made with small amateur telescopes. Assuming their distances to be 7.4 Mpc, the sa…
