## 4. General solution of the basic equations with ,Eliminating mass between Eqs. (1) and (2) we arrive at where is the ablation term and is the deceleration term. Here means natural logarithm. If the ablation term is identically (for all time instants) equal to the deceleration term, then K = constant. Eq. (10) and represent
a complete solution. Similar numerical procedure as for the case
with constant and Eq. (10) contains two unknown functions , . Assuming one of them, the other is resulting from (10). If we could determine as well as from the observed distances, we would be able to compute and then from Eq. (10) also . This will be described in details in the next section. Once we have solved Eq. (10), mass and ablation are given as © European Southern Observatory (ESO) 2000 Online publication: June 5, 2000 |
