In this long term, environmental conditions will change with time and will be different than they are at present, especially because of and after remediation. For purposes of predicting water quality, it is therefore essential to accurately determine...

I show that in some binary systems under a narrow range of parameters, a substantial fraction of the giant stellar envelope is lost before the onset of the common envelope. The reduced envelope mass at the onset of the common envelope implies that the binary system emerges from the commo...
