cds-question@unistra.frnovaeradio-sourcesastronomical-reference-materialsWe present radio observations (1-40GHz) for 36 classical novae, representing data from over five decades compiled from the literature, telescope archives, and our own programs. Our targets display a striking diversity in their optical parameters (e.g., spanning optical fading timescales, t_2_=1-263days), and we find a similar diversity in the radio light curves. Using a brightness temperature analysis, we find that radio emission from novae is a mixture of thermal and synchrotron emission, with nonthermal emission observed at earlier times. We identify high brightness temperature emission (T_B_>5x10^4^K) as an indication of synchrotron emission in at least nine (25%) of the novae. We find a class of synchrotron-dominated novae with mildly evolved companions, exemplified by V5589 Sgr and V392 Per, that appear to be a bridge between classical novae with dwarf companions and symbiotic binaries with giant companions. Four of the novae in our sample have two distinct radio maxima (the first dominated by synchrotron and the later by thermal emission), and in four cases the early synchrotron peak is temporally coincident with a dramatic dip in the optical light curve, hinting at a common site for particle acceleration and dust formation. We publish the light curves in a machine- readable table and encourage the use of these data by the broader community in multiwavelength studies and modeling efforts.2021ApJS..257...49Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/257/49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cb : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2004)II/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-2005)V/113 : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2003)J/A+A/480/611 : XMM-Newton slew survey catalogue, XMMSL1 (Saxton+, 2008)J/ApJS/187/275 : Photometric histories of recurrent novae (Schaefer, 2010)J/AJ/140/34 : Classification of nova light curves (Strope+, 2010)J/ApJS/197/31 : Swift X-ray obs. of classical novae.
