1 Massive stars, massive close binaries, Wolf-Rayet stars, stellar winds, mass loss in hot stars, stellar wind theories were hot topics during the eighties and many symposia were devoted to this types of research Massive stars, massive close binaries, Wolf-Rayet stars, stellar winds, mass loss in hot stars, stellar wind theories were hot topics during the eighties and many symposia were devoted to this types of research Theories -sometimes controversial- were developed and defended with enthusiasm Theories -sometimes controversial- were developed and defended with enthusiasm

5 Ed: X-rays will appear near the end of close binary evolution when the initial secondary approaches its Roche lobe Ed: X-rays will appear near the end of close binary evolution when the initial secondary approaches its Roche lobe He strongly argued that given the time scales there ought to be many more OB- stars with NS (or BH) companions which had not yet begun to to produce X-rays He strongly argued that given the time scales there ought to be many more OB- stars with NS (or BH) companions which had not yet begun to to produce X-rays Peter Conti felt that this could not be right Peter Conti felt that this could not be right

6 As we know now, the X-ray production starts pretty early in the process after the production of the NS (BH) And the (initial secondary) wind is already blowing and feeding the collapsed object,

7 We went for an excursion on a boat. During that excursion Peter and Ed had a vivid discussion on this particular point, and this led to a bet: We went for an excursion on a boat. During that excursion Peter and Ed had a vivid discussion on this particular point, and this led to a bet: Ed’s statement: There are at least 10 (maybe 5) OB stars in the Bright Star Catalogue (brighter than V=6,5) that have NS (BH) companions, but no X-rays Ed’s statement: There are at least 10 (maybe 5) OB stars in the Bright Star Catalogue (brighter than V=6,5) that have NS (BH) companions, but no X-rays Peter did not agree Peter did not agree The bet was to check this within two years (1985) the loser should offer a bottle of Romanée-Conti The bet was to check this within two years (1985) the loser should offer a bottle of Romanée-Conti I should be referee I should be referee We thought, simple minds as we are, that the price was something like 50 $ We thought, simple minds as we are, that the price was something like 50 $

8 The rest of the story occurs in Boulder Ed buys a bottle of Romanée-Conti....

9 So, Ed asked AnneMike, when she went to the grocers to get her purchases for the kitchen, to add a case of Romanée-Conti. In the shop she was sent over to a wine store. She was greeted with consternation over her request for a case, but she managed to get a single bottle for a few hundred $. When Peter and Carolyn were both in Holland Ed gave them the bottle and they brought it home. It rested a year or two and was opened when Ed, myself and my spouse were in Boulder for a conference at the university. Carolyn had cooked for the five of us. Only the poor AnneMike was lacking at the party.

18 Now, Peter and I feel a little bit guilty: the poor guy Ed had to take a mortgage on his house to pay off the price of a Roman é e-Conti (at this moment it is approximately 3750 € or 5000 $) Now, Peter and I feel a little bit guilty: the poor guy Ed had to take a mortgage on his house to pay off the price of a Roman é e-Conti (at this moment it is approximately 3750 € or 5000 $) So we offer him a new bottle of wine... So we offer him a new bottle of wine...
