From Hale-Bopp’s Activity to Properties of Its Nucleuster. A thermal model has been applied to calculate gas production rates of Hale-Bopp. The strong obliquity of the spin axis causes pronounced seasonal effects and, therefore, an asymmetry of water activity with respect to perihelion. By comparing measured and calculated rates properties of the nucleus have been derived.

A Study of Non-Gravitational Effects of Comet C/1995 O1 Hale-Bopponal observations in the pure gravitational case, as well as in the non-gravitational case. The calculations showed that the comet’s motion is predictable only over an interval of a few orbital periods. The statistical conclusions change significantly when non-gravitational effects are included in the analysis.

,Changes in Farmers’ Work and Life,entric distances. We present the results of our observing campaign at radio wavelengths which began in August 1995 and ended in January 2002. The observations were carried out with the telescopes of Nançay, IRAM, JCMT, CSO and, since September 1997, SEST. The lines of nine molecules (OH, CO, HCN, CH
