Effects Of Rim Width On Tractor Tire Performance

An Extended Grid of Nova Models. Iii. Very Luminous, Red Novae

“…The extraordinary light echoes (Ritchey 1901;Couderc 1939), and ejected shells of matter (Ritchey 1917) associated with GK Per are the obvious hallmarks of a highly energetic, mass-ejecting event. The detection of erupting classical novae in the Small Magellanic Cloud (McKibben 1951), Large Magellanic Cloud (Gill 1927) and in M31 (Hubble 1929) established novae as ubiquitous beacons radiating at tens of thousands of times the luminosity of the Sun or more -a new class of astrophysical phenomenon (Harwit 1981). Over the past century, of the order of a thousand erupting classical novae have been detected in the Galaxy, in galaxies of the Local Group (Ciardullo et al 1990), ) and as far away as the Virgo (Ferrarese et al 2003;Shara et al 2004) and Fornax clusters (Neill & Shara 2004).…”
