The recurrent nova T CrB had prior eruptions observed near December 1787 and October 1217 AD

Bradley E. Schaefer

The famous recurrent nova (RN) T Coronae Borealis (T CrB) has had observed eruptions peaking at a visual magnitude of 2.0 in the years 1866 and 1946, while a third eruption is now…

Orbital Period Changes for Fourteen Novae and the Critical Failures of the Predictions of Standard Theories, the Hibernation Model, and the Magnetic Braking Model

Bradley E. Schaefer

The evolution of novae and Cataclysmic Variables (CVs) is driven by changes in the binary orbital periods. In a direct and critical test for various evolution models and their phys…

The B & V Light Curves for Recurrent Nova T CrB From 1842--2022, the Unique Pre- and Post-Eruption High-States, the Complex Period Changes, and the Upcoming Eruption in 2025.51.3

Bradley E. Schaefer

T CrB is one of the most-famous and brightest novae known, and is a recurrent nova with prior eruptions in 1866 and 1946 that peak at =2.0. I have constructed light curves spann…

The Path from the Chinese and Japanese Observations of Supernova 1181 AD, to a Type Iax Supernova, to the Merger of CO and ONe White Dwarfs

Bradley E. Schaefer

In 1181 AD, Chinese and Japanese observers reported an unmoving bright `Guest Star' in the constellation Chuanshe, visible for 185 days. In 2013, D. Patchick discovered what turned…

The Nova KT Eri Is a Recurrent Nova With a Recurrence Time-Scale of 40-50 Years

Bradley E. Schaefer, Frederick M. Walter, Rebekah Hounsell +1

KT Eridani was a very fast nova in 2009 peaking at V=5.42 mag. We marshal large data sets of photometry to finally work out the nature of KT Eri. From the TESS light curve, as conf…

Comprehensive Catalogue of the Overall Best Distances and Properties of 402 Galactic Novae

Bradley E. Schaefer

I derive the overall best distances for all 402 known galactic novae, and I collect their many properties. The centrepiece is the 74 novae with accurate parallaxes from the new Gai…
