| 41. | This is a single-lined spectroscopic binary system.
|
| 42. | Work in September 2005 also aimed to begin spectroscopic studies on 260 Sg.
|
| 43. | Its orbit was computed in 1946 from spectroscopic observations.
|
| 44. | The second component is a spectroscopic binary star system.
|
| 45. | In the past it was suggested that it may be a spectroscopic binary.
|
| 46. | The structure of the pigment was determined by spectroscopic methods and chemical transformations.
|
| 47. | NMR spectroscopic experiments indicated close proximity of the aldehyde and the aryl ring.
|
| 48. | These objects were selected using the KPNO International Spectroscopic Survey ( KISS ).
|
| 49. | Euclid will measure spectroscopic redshifts for 50 million objects.
|
| 50. | The system is both a visual and spectroscopic binary.
