Top] [Prev] [Next] . In order to discover and determine some characteristics of extra-solar earth-like planets, J. R. P. Angel has defined several spacecraft experiments (labelled Oases 1 and 2). We have examined some aspects of these experiments and believe at least one, and possibly two, significant improvements could be made economically. The paper briefly discusses several features of redundant coronagraphs, and indicates one way that they might be incorporated into flight apparatus. ...

Next: The Orion OB1 Up: Contents Previous: This work . In this chapter, I will define the sample of stars which will be discussed throughout the remainder of the dissertation. I define two coeval sets of PMS stars located in the Orion OB1 association. ... I then describe the X--ray observations which were used to find the PMS stars in this association. After this, I spend several sections detailing the photometric observations and difficulties in placing objects on the H--R diagram. ...
