Lunar Occultations of Stars with Exoplanet Candidates
We investigate the potential of lunar occultations for the detection of very faint companions, and in particular for the possibility of detecting extrasolar planets. We review the basic concepts of the method, and discuss the quantities which are relevant for this particular application. The near-infrared range, and in particular the K and L bands (2.2 and 3.6m), ooer the best dynamic range. We...
متن کاملNew binary stars discovered by lunar occultations . V ?
We present recent results from our ongoing lunar occultation program on binary stars at the TIRGO and Calar Alto observatories. Observations are presented here for a total of seventeen sources, the majority of which are resolved for the first time. These include SAO 94621, IRAS 18154-1900, SAO 98345, SAO 98363, SAO 93947, SAO 97319, SAO 97437, SAO 94986, SAO 94488, DO 11742, SAO 78027 and SAO 7...
متن کاملNew binary stars discovered by lunar occultations. III
We report on a total of 20 occultation events of 16 binary sources, observed in the near infrared in the course of routine lunar occultation programs at the TIRGO andCalar Alto observatories. The results consist in either discoveries of new binaries, or in re-observations of known or suspected binaries where only incomplete information was available. This paper is the third in a series of simil...

We report on a total of 20 sources observed in the near infrared in the course of routine lunar occultation programs at the TIRGO and Calar Alto observatories. The results consist either in discoveries of new binaries, or in re–observations of known or suspected binaries where only incomplete information was previously available. For the first time, a companion has been detected around the foll...
