Dynamics of the CO+ coma of comet 29P/Schwasmann-Wachmann 1
O. Ivanova, O. Agapitov, D. Odstrcil +3
Comet-centaur 29P/Schwassmann-Wachmann 1 was observed in CO+ emission and contin-uum during 2007-2009 using the 6-m Big Telescope Alt-azimuth at the Special Astrophysical Observato…
Dust productivity and impact collision of the asteroid (596) Scheila
L. Neslusan, O. Ivanova, M. Husarik +2
Photometric observations of asteroid (596) Scheila were obtained during and after its 2010 outburst. The estimated radius of the body (spherical approximation of the asteroidal bod…
Results of Complex Observations of Asteroid (596) Scheila at the Sanglokh International Astronomical Observatory
G. I. Kokhirova, O. V. Ivanova, F. Dzh. Rakhmatullaeva +3
Results of astrometric and BVRI photometric observations of the active asteroid (596) Scheila are presented. The observations were carried out at the Zeiss 1000 telescope of the Sa…
Astrometric and photometric observations of comet 29P/Schwassmann--Wachmann 1 at the Sanglokh international astronomical observatory
G. I. Kokhirova, O. V. Ivanova, F. Dzh. Rakhmatullaeva +2
Astrometric and photometric observations of the comet 29P/Schwassmann-Wachmann 1 were performed at the Zeiss-1000 telescope of the International Astronomical Observatory Sanglokh (…
The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56
We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
An enhanced slope in the transmission spectrum of the hot Jupiter WASP-104b
G. Chen, E. Palle, H. Parviainen +25
We present the optical transmission spectrum of the hot Jupiter WASP-104b based on one transit observed by the blue and red channels of the DBSP spectrograph at the Palomar 200-inc…
Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objects and Centaurs
F. L. Rommel, F. Braga-Ribas, J. Desmars +66
Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Ste…
Vacuum ultraviolet photoabsorption spectroscopy of space-related ices: 1 keV electron irradiation of nitrogen- and oxygen-rich ices
S. Ioppolo, Z. Kanuchová, R. L. James +5
Molecular oxygen, nitrogen, and ozone have been detected in the Solar System. They are also expected to be present in ice-grain mantles within star-forming regions. Laboratory expe…
The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90
Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…
