Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact
G. P. Tozzi, H. Boehnhardt, L. Kolokolova +15
On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material ejected by the impact expa…
The enigma of the oldest `nova': the central star and nebula of CK Vul
M. Hajduk, Albert A. Zijlstra, P. A. M. van Hoof +9
CK Vul is classified as, amongst others, the slowest known nova, a hibernating nova, or a very late thermal pulse object. Following its eruption in AD 1670, the star remained visib…
The onset of photoionization in Sakurai's Object (V4334 Sgr)
P. A. M. van Hoof, M. Hajduk, Albert A. Zijlstra +6
We investigate the reheating of the very late thermal pulse (VLTP) object V4334 Sgr (Sakurai's Object) using radio observations from the Very Large Array, and optical spectra obtai…
V605 Aql: The Older Twin of Sakurai's Object
Geoffrey C. Clayton, F. Kerber, N. Pirzkal +3
New optical spectra have been obtained with VLT/FORS2 of the final helium shell flash (FF) star, V605 Aql, which peaked in brightness in 1919. New models suggest that this star is…
The Real-Time Evolution of Sakurai's Star (V4334 Sgr) and other (V)LTP Objects
P. A. M. van Hoof, M. Bryce, A. Evans +10
We report on the progress of our on-going campaign to monitor the evolution of the VLTP objects V4334 Sgr and V605 Aql, as well as the suspected (V)LTP object CK Vul. V4334 Sgr doe…
On the discovery of an enormous ionized halo around the hot DO white dwarf PG1034+001
Thomas Rauch, Florian Kerber, Eva-Maria Pauli
Very recently, the discovery of the largest known planetary nebula on the sky surrounding the DO white dwarf PG1034+001 with an apparent diameter of about 2 degrees, corresponding…
