The Tau Ceti traveler
 The Tau Ceti traveler is a relativistic problem imagined by Dr. Richard Hachel and which consists of the study of the journey to Tau Ceti of an astronaut evolving in accelerated mode of approximately 10m/s², in order to maintain his ship in a sort of artificial gravitation.
The distance of Tau Ceti is set at twelve light years.
The departure is from the Cape Canaveral base in Florida.
We set:
a=1.052ly/y²
D=12al

 Do both "ly" and "al" mean 'light year? If they do, you should use the
same symbol for both.

  Yes. Light-year is année-lumière. ly=al.

 You should also say what D means.

 D=distance (in the two language). 

We want to know when and at what speed the spaceship will cross the Tau Ceti system in the Earth's frame of reference.

 Do you mean that the astronaut is flying past tau Ceti without stopping
there?

 Without stopping nor decelerate.  R.H.
