AAS Division on Dynamical Astronomy Newsletter 79, February 1995

Chris Hunter will give his Brouwer Award lecture entitled "Bending Waves in Flattened Stellar Systems." Ray Duncombe will be the banquet speaker and will commemorate the 25th anniversary of the DDA with a history of the Division. Bob Hanson will give an invited lecture entitled "The Lick Northern Proper Motion (NPM) Catalogs: A Database for Galactic Studies" and Jeff Cuzzi will give an invited lecture entitled "Planetary Rings Update."

Yosemite is, of course, one of the jewels of the national park system. There are tremendous opportunities for hiking, camping, rock climbing, bus and tram tours, bicycling, ranger walks, and horse back riding. Details about the park and activities can be obtained by asking for the vacation planning materials from Yosemite reservations at (209) 252-4848. This will be a perfect meeting to bring your family. In late April the weather can be wet and/or cold so one should prepare accordingly.

We had good response to the request in the last Newsletter for an indication from people as to whether or not they intended to come to this meeting. 25 people have said that they intend to come and another 4 have said that they may attend. A list of these people, along with any available information on the talk(s) they may give, appears at the end of this Newsletter.

Lodging Arrangements

Please return the attached meeting registration form to Roy by March 20. The meeting registration fee is $25. The banquet fee is $30. Meals can be purchased in the Lodge for the customary restaurant prices. Picnicking supplies are readily available in the valley and can save the expense of some restaurant meals.

Members can fly into either San Francisco or, better yet, into Fresno. Yosemite is a four hour drive from San Francisco and a one and a half hour drive from Fresno. Once arrived at the Lodge in Yosemite Valley, a car is not necessary since there is excellent shuttle service around the valley; therefore participants can save money by car pooling.

Mark Abstract "DDA"

When you fill out the abstract template, be sure to indicate that your abstract is for the DDA meeting, NOT the AAS 186th meeting in Pittsburg. To do this, type DDA in the /societysig line. It should look like the following:

/societysig{DDA}                                   %OPTIONAL

Electronic Acknowledgment of Abstract Receipt

Incoming abstracts are usually processed within 24 hours. The abstracts are accepted and assigned running identification numbers during this stage, and you should receive a second message confirming the acceptance of your abstract and notifying you of the running number. If you do not receive a confirmation, DO NOT RESUBMIT THE ABSTRACT. Please contact the Executive Office by calling 202-328-2010 or by sending e-mail to abs-help@aas.org. If you submit the abstract more than once, you are likely to be charged more than once as well. Contacting the Executive Office will help avoid this inconvenience.

MEETING ANNOUNCEMENT

It has become clear over the past few years that the role played by binary stars in the dynamical evolution of star clusters is critical (see, for example the major summary by Hut 104, 981, 1992). Both open and globular star clusters have been the objects of recent studies of the relationship between binary stars and the 'blue stragglers' (stars that are too blue for their luminosities, if normal evolution of single stars had produced them). The merged products of binary star evolution may be possible paths to these and related anomalous objects. In any case, the dynamical evolution of systems influences their environments and vice versa; the results of these enquiries are important for understanding the existence and role of the objects as standard candles. Thus the meeting has ramifications beyond the subject areas.
