Aims.We report on spectrally dispersed interferometric AMBER/VLTI observations of the recurrent nova RS Oph five days after the discovery of its outburst on 2006 Feb. 12. Methods: Using three baselines ranging from 44 to 86 m, and a spectral resolution of λ/δλ=1500, we measured the extension of the milliarcsecond-scale emission in the K band continuum and in the Brγ and He I 2.06 μm lines, allowing us to get an insight into the kinematics of the line forming regions. The continuum visibilities…

Spectro-interferometric observations of classical nova V458 Vul 2007
We used the Palomar Testbed Interferometer (PTI) to resolve 2.2 $\mu$m emission from the classical nova V458 Vul 2007 over the course of several days following its discovery on 2007 August 8.54 UT.
VLTI monitoring of the dust formation event of the Nova V1280 Scorpii
Context. We present the first high spatial resolution monitoring of th e dust forming nova V1280 Sco performed with the Very Large Telescope Interferometer (VLTI). Aims. These observations aim at
MILLIARCSECOND N-BAND OBSERVATIONS OF THE NOVA RS OPHIUCHI: FIRST SCIENCE WITH THE KECK INTERFEROMETER NULLER
We report observations of the nova RS Ophiuchi (RS Oph) using the Keck Interferometer Nuller (KIN), approximately 3.8 days following the most recent outburst that occurred on 2006 February 12. These
The 2011 outburst of the recurrent nova T Pyxidis. Evidence for a face-on bipolar ejection
We report on near-IR interferometric observations of the outburst of the recurrent nova T Pyx. We obtained near-IR observations of T Pyx at dates ranging from t=2.37d to t=48.2d after the outburst,
Milliarcsecond Resolution Infrared Observations of the Recurrent Nova RS Ophiuchi and Low Mass Stellar Systems
We introduce the method of long-baseline stellar interferometry starting with the fundamental combination of electric fields. We describe beam combination techniques and how they are realized at the
THE EXPANDING NEBULAR REMNANT OF THE RECURRENT NOVA RS OPHIUCHI (2006). II. MODELING OF COMBINED HUBBLE SPACE TELESCOPE IMAGING AND GROUND-BASED SPECTROSCOPY
We report Hubble Space Telescope (HST) imaging, obtained 155 and 449 days after the 2006 outburst of the recurrent nova RS Ophiuchi, together with ground-based spectroscopic observations, obtained
The SSS Phase of RS Ophiuchi Observed with Chandra and XMM-Newton. I. Data and Preliminary Modeling
TLDR
The bound-free absorption by neutral elements in the line of sight, resonance absorption lines plus self-absorbed emission-line components, collisionally excited emission lines from the shock, He-like intersystem lines, and spectral changes during an episode of high-amplitude variability are discussed.
CHANDRA DETECTION OF EXTENDED X-RAY EMISSION FROM THE RECURRENT NOVA RS OPHIUCHI
Radio, infrared, and optical observations of the 2006 eruption of the symbiotic recurrent nova RS Ophiuchi showed that the explosion produced non-spherical ejecta. Some of this ejected material was
THE SUPERSOFT X-RAY PHASE OF NOVA RS OPHIUCHI 2006
TLDR
Measurements are consistent with a WD mass near the Chandrasekhar limit; combined with a deduced accumulation of mass transferred from its binary companion, this leads to suggest that RS Oph is a strong candidate for a future supernova explosion.

No Expanding Fireball: Resolving the Recurrent Nova RS Ophiuchi with Infrared Interferometry
Following the recent outburst of the recurrent nova RS Oph on 2006 February 12, we measured its near-infrared size using the IOTA, Keck, and PTI Interferometers at multiple epochs. The characteristic
The 1985 outburst of RS Ophiuchi: Spectroscopic results
Optical spectroscopic data on the recurrent nova RS Ophiuchi obtained between 32 and 108 days after its last outburst on 1985 January 27 are presented. RS Oph was in the coronal-line phase at that

RS Ophiuchi began its latest outburst on 2006 February 12. Previous outbursts have indicated that high-velocity ejecta interact with a preexisting red giant wind, setting up shock systems analogous
Few Skewed Disks Found in First Closure-Phase Survey of Herbig Ae/Be Stars

An asymmetric shock wave in the 2006 outburst of the recurrent nova RS Ophiuchi
TLDR
The detection of spatially resolved structure in RS Ophiuchi from two weeks after its 12 February 2006 outburst is reported, producing a remnant similar to that of a type II supernova but evolving over months rather than millennia.
Radio observations of the 1985 outburst of RS Ophiuchi
The paper reports observations of the first radio source observed in association with a recurrent nova event, the 1985 January 26 outburst of RS Ophiuchi. Measurements at some or all of four VLA

We report a coordinated multiband photometry of the RS Oph 2006 outburst and highlight the emission-line-free y-band photometry that shows a midplateau phase at y ~ 10.2 mag from day 40 to day 75
RS Ophiuchi — first radio detection of a recurrent nova outburst
Recurrent novae and classical novae belong to the cataclysmic variable class of objects. Of these, only classical novae outbursts have been hitherto observed at radio wavelengths, and then no earlier
