The Symbiotic Recurrent Nova V745 Sco at Radio Wavelengths
Isabella Molina, Laura Chomiuk, Justin D. Linford +14
V745 Sco is a Galactic symbiotic recurrent nova with nova eruptions in 1937, 1989 and 2014. We study the behavior of V745 Sco at radio wavelengths (0.6-37,GHz), covering both its 1…
Classical Novae at Radio Wavelengths
Laura Chomiuk, Justin D. Linford, Elias Aydi +20
We present radio observations (1--40 GHz) for 36 classical novae, representing data from over five decades compiled from the literature, telescope archives, and our own programs. O…
Shocks and dust formation in nova V809 Cep
Aliya-Nur Babul, Jennifer L. Sokoloski, Laura Chomiuk +5
The discovery that many classical novae produce detectable GeV -ray emission has raised the question of the role of shocks in nova eruptions. Here we use radio observations of n…
X-ray evolution of the nova V959 Mon suggests a delayed ejection and a non-radiative shock
Thomas Nelson, Koji Mukai, Laura Chomiuk +7
X-ray observations of shocked gas in novae can provide a useful probe of the dynamics of the ejecta. Here we report on X-ray observations of the nova V959 Mon, which was also detec…
T CrB: Radio Observations During the 2016--2017 "Super-Active" State
Justin D. Linford, Laura Chomiuk, Jennifer L Sokoloski +6
We obtained radio observations of the symbiotic binary and known recurrent nova T Coronae Borealis following a period of increased activity in the optical and X-ray bands. A compar…
Regulation of accretion by its outflow in a symbiotic star: the 2016 outflow fast state of MWC 560
Adrian B. Lucy, J. L. Sokoloski, U. Munari +11
How are accretion discs affected by their outflows? To address this question for white dwarfs accreting from cool giants, we performed optical, radio, X-ray, and ultraviolet observ…
The Peculiar Multi-Wavelength Evolution Of V1535 Sco
J. D. Linford, L. Chomiuk, T. Nelson +8
We present multi-wavelength observations of the unusual nova V1535 Sco throughout its outburst in 2015. Early radio observations were consistent with synchrotron emission, and earl…
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…
Binary orbits as the driver of gamma-ray emission and mass ejection in classical novae
Laura Chomiuk, Justin D. Linford, Jun Yang +16
Classical novae are the most common astrophysical thermonuclear explosions, occurring on the surfaces of white dwarf stars accreting gas from companions in binary star systems. Nov…
The 2011 Outburst of Recurrent Nova T Pyx: X-ray Observations Expose the White Dwarf Mass and Ejection Dynamics
Laura Chomiuk, Thomas Nelson, Koji Mukai +9
The recurrent nova T Pyx underwent its sixth historical outburst in 2011, and became the subject of an intensive multi-wavelength observational campaign. We analyze data from the S…
The Radio Light Curve of the Gamma-Ray Nova in V407 Cyg: Thermal Emission from the Ionized Symbiotic Envelope, Devoured from Within by the Nova Blast
Laura Chomiuk, Miriam I. Krauss, Michael P. Rupen +10
We present multi-frequency radio observations of the 2010 nova event in the symbiotic binary V407 Cygni, obtained with the Karl G. Jansky Very Large Array and spanning 1-45 GHz and…
