VX Hya (2008-2009): modelling the 2008 observations

Comparison with observations

Red line: the model, Green dots: my observations (V band).

Comparison with Fitch's model

In 2008 I found that my observations were too early by 3.7 hours from the model of Fitch (1966). When my model is compared with the one of Fitch, this shift shows up again:


Red: my model, Blue: the 1st part of the 1st order of the model of Fitch (1966).
