a) A parallax was expected, according to theory.b) None was detected.
The problem here is that even the closest star (apart from the Sun) are so far away that their parallax is less than one arc-second - i.e., less than 1/3600 of a degree, and therefore hard to measure.

Why has the heliocentric model been replaced with the geocentric model?
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
What is a good sentence for heliocentric?
The scientist made the heliocentric model of the solar system. It is a word for the graphical model of our solar system.
What are the strengths of the heliocentric model?
Its main strength is that it is the model which is universally accepted by everyone. Copernicus put forward a heliocentric model that used circular orbits. That meant he couldn't completely eliminate all the complications of the old geocentric model, such as "epicycles". Later Kepler showed that the planets move in elliptical orbits. The basic idea of the heliocentric model is that the Sun is at the centre. One of the main strengths is the simplicity of the heliocentric model. Kepler's version (still used today) of the model with its elliptical orbits is particularly elegant and simple, with no epicycles.

Did Copernicus believe in a heliocentric model?
Copernicus published an alternative model of the planets' movement in 1543 that had the Sun at the centre. It was the first heliocentric model. It used orbits based on combinations of circles, as the ancient Ptolemaic system had done, which was geocentric. In Copernicus's model the paths followed by the planets were less complicated, but other than that Copernicus had no way of proving if it was right or not at that time, so it isn't known whether he believed in it.
Who introduced the idea of a heliocentric model of telescope that uses mirrors?
I believe you are confusing two things here; there is no such thing as a "heliocentric model of telescope". There is a heliocentric model of our Solar System, and there are telescopes. The two are unrelated.
Where is the heliocentric model of the location of earth?

What are the geocentric and heliocentric theories of the universe?
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
What is a sun - centered model?
