Discovery of two distinct polarimetric behaviours of trans-Neptunian objects
S. Bagnulo, I. Belskaya, K. Muinonen +4
Trans-Neptunian objects (TNOs) contain the most primitive and thermally least-processed materials from the early accretional phase of the solar system. They allow us to study inter…
Photometry and polarimetry of the nucleus of comet 2P/Encke
H. Boehnhardt, G. P. Tozzi, S. Bagnulo +3
Broadband imaging photometry, and broadband and narrowband linear polarimetry was measured for the nucleus of 2P/Encke over the phase-angle range 4 - 28 deg. An analysis of the poi…
(42355) Typhon-Echidna: Scheduling Observations for Binary Orbit Determination
W. M. Grundy, K. S. Noll, J. Virtanen +6
We describe a strategy for scheduling astrometric observations to minimize the number required to determine the mutual orbits of binary transneptunian systems. The method is illust…
Polarimetry of the dwarf planet (136199) Eris
I. Belskaya, S. Bagnulo, K. Muinonen +4
We investigate the surface characteristics of the large dwarf planet (136199) Eris. With the FORS1 instrument of the ESO VLT, we have obtained Bessell broadband R linear polarimetr…
Exploring the surface properties of Transneptunian Objects and Centaurs with polarimetric FORS1/VLT observations
S. Bagnulo, H. Boehnhardt, K. Muinonen +3
Polarization is a powerful remote-sensing method to investigate solar system bodies. It is an especially sensitive diagnostic tool to reveal physical properties of the bodies whose…
