Most comets are volatile-rich bodies that have recently entered the inner solar system
following long-term storage in the Kuiper belt and the Oort cloud reservoirs. These reservoirs …

CO and CO 2 are the two dominant carbon-bearing molecules in comae and have major
roles in driving activity. Their relative abundances also provide strong observational …

Abstract 29P/Schwassmann–Wachmann is an unusual solar system object. Originally
classified as a short-period comet, it is now known as a Centaur that recently transferred to …

We measure the photometric color in the inner coma of Comet 29P/Schwassmann–
Wachmann 1 on nine nights in August and October, 2018. We see variations in the color …

We present visible and mid-infrared imagery and photometry of temporary Jovian co-orbital
comet P/2019 LD 2 taken with Hubble Space Telescope/Wide Field Camera 3 (HST/WFC3) …

Abstract Centaur 29P/Schwassmann–Wachmann 1 (SW1) is a highly active object orbiting
in the transitional" Gateway" region between the Centaur and Jupiter-family comet (JFC) …

Multi-band photometric monitoring of comet 29P/Schwassmann–Wachmann 1 was
conducted with the standard Johnson–Cousins filter set. Observations extended from 2018 …

Cometary outbursts, ie a sudden increase in brightness, have aroused astronomers'
curiosity since the 1920s (Hughes). In 1927, Comet 29P/Schwassmann–Wachmann 1 was …

In the paper we examine two selected mechanisms of matter ejection from the cometary
nuclei. The first is a calm sublimation from the comet's nucleus and the second is the …

This paper discusses the influence of light pollution of the night sky on the conditions of
visibility of astronomical objects such as planets, stars and comets. This phenomenon has a …
