Next: Biases Up: Contents Previous: Stars without Periods . Based on the data presented in Figure , I can suggest several conclusions about the evolution of young stars. The results of the Kolmogorov--Smirnov (KS) tests with the data presented here and those of Choi & Herbst (1996) on similar regions of the histogram indicate that there is something which holds stars near eight day periods. Stars in different regions also seem to share a similar mechanism which regulates the fast rotators. ...

It is necessary to specify the coordinate system for the drilling of plug-plates so that the drilling file (currently named plPlugMap), plate drilling, cartridge, rotator wrap and the rotator itself are compatible. ...

... Keywords: DVD DVD-ROM MPEG ISO9660 . ... I know Linux should support any SCSI or IDE DVD-ROM drive, but so far (at least to my knowledge), it'll only act like a CD-ROM drive. I really don't know much about the DVD standard (if anybody knows, please point me to some documentation!), but my guess is that DVD-ROM discs (I think I saw Walnut Creek selling 4.7 gigs of stuff on one disc) would probably just be the same ISO9660 standard, so there wouldn't be any need to support anything extra with that. ...

... Cross-shaped galaxy ZGC 2315+03 (Fig.1) has been described by Zwicky (1971) as ``post-eruptive or the result of the crossing of a compact galaxy through an edge-on spiral'' . This object was included in the Polar-Ring Catalog (C-71) by Whitmore et al. (1990) as a possible candidate for Polar-Ring Galaxies (PRG). ... One of them is galaxy 'disk' and the other is 'polar-ring'. ... The facts against the polar-ring nature of ZGC 2315+03 can be summarized as follows: . ...

There is some interest concerning whether or not the Mars Global Surveyor Orbiter Camera (MOC) will observe the "Face on Mars" and other features in the Cydonia region on Mars. ... For those not familiar with the topic, several Viking images show features on the surface of Mars that, in the eyes of some people, resemble "faces," "pyramids," and other such "artifacts." ... But nothing can be done about the orbit spacing or the pointing control or the width of the MOC field of view. ... Mars Face . ...
