Breaking the habit - the peculiar 2016 eruption of the unique recurrent nova M31N 2008-12a
M. Henze, M. J. Darnley, S. C. Williams +70
Since its discovery in 2008, the Andromeda galaxy nova M31N 2008-12a has been observed in eruption every single year. This unprecedented frequency indicates an extreme object, with…
Multiwavelength observations of nova SMCN 2016-10a --- one of the brightest novae ever observed
E. Aydi, K. L. Page, N. P. M. Kuin +17
We report on multiwavelength observations of nova SMCN 2016-10a. The present observational set is one of the most comprehensive for any nova in the Small Magellanic Cloud, includin…
Inflows, Outflows, and a Giant Donor in the Remarkable Recurrent Nova M31N 2008-12a? - Hubble Space Telescope Photometry of the 2015 Eruption
M. J. Darnley, R. Hounsell, P. Godon +14
The recurrent nova M31N 2008-12a experiences annual eruptions, contains a near-Chandrasekhar mass white dwarf, and has the largest mass accretion rate in any nova system. In this p…
The Distance to Nova V959 Mon from VLA Imaging
J. D. Linford, V. A. R. M. Ribeiro, L. Chomiuk +7
Determining reliable distances to classical novae is a challenging but crucial step in deriving their ejected masses and explosion energetics. Here we combine radio expansion measu…
Obscuration effects in Super-Soft-Source X-ray spectra
J. -U. Ness, J. P. Osborne, M. Henze +11
Super-Soft-Source (SSS) X-ray spectra are blackbody-like spectra with effective temperatures ~3-7x10^5 K and luminosities of 10^{35-38} erg/s. SSS grating spectra display atmospher…
Morpho-Kinematical Modelling of Nova Eridani 2009 (KT Eri)
V. A. R. M. Ribeiro, M. F. Bode, M. J. Darnley +3
Modelling the morphology of a nova outburst provides valuable information on the shaping mechanism in operation at early stages following the outburst. We performed morpho-kinemati…
Optical Morphology, Inclination and Expansion Velocity of the Ejected Shell of Nova Monocerotis 2012
V. A. R. M. Ribeiro, U. Munari, P. Valisa
The morphology of the ejected shell of the He/N Nova Monocerotis 2012 outburst was studied in detail. Synthetic line profile spectra were compared to the [O {\sc iii}] 4959,5007 Å…
On the pulse-width statistics in radio pulsars. III. Importance of the conal profile components
K. Maciesiak, J. Gil, G. Melikidze
This work is a continuation of two previous papers of a series, in which we examined the pulse-width statistics of normal radio pulsars. In the first paper we compiled the largest…
On the Progenitors of Galactic Novae
M. J. Darnley, V. A. R. M. Ribeiro, M. F. Bode +2
Of the approximately 400 known Galactic classical novae, only ten of them, the recurrent novae, have been seen to erupt more than once. At least eight of these recurrents are known…
On the Progenitor System of Nova V2491 Cygni
M. J. Darnley, V. A. R. M. Ribeiro, M. F. Bode +1
Nova V2491 Cyg is one of just two detected pre-outburst in X-rays. The light curve of this nova exhibited a rare "re-brightening" which has been attributed by some as the system be…
The Expanding Nebular Remnant of the Recurrent Nova RS Ophiuchi (2006): II. Modeling of Combined Hubble Space Telescope Imaging and Ground-based Spectroscopy
V. A. R. M. Ribeiro, M. F. Bode, M. J. Darnley +16
We report Hubble Space Telescope imaging, obtained 155 and 449 days after the 2006 outburst of the recurrent nova RS Ophiuchi, together with ground-based spectroscopic observations…
Introducing Astronomy into Mozambican Society
V. A. R. M. Ribeiro, C. M. Paulo, A. M. A. R. Besteiro +4
Mozambique has been proposed as a host for one of the future Square Kilometre Array stations in Southern Africa. However, Mozambique does not possess a university astronomy departm…
