... Journal: 1973, Astron Zh., ... The isotopic shifts of helium spectral lines have been measured for four high velocity OB-stars and one standard star. The spectrograms were secured at 2.6 m reflector of the Grimean observatory, dispersion beging 8 / mm . All five stars did not show the systematic isotopic shifts. But three lines of 53 Ari have shown shifts which are in agreement with theoretical ones, but other helium lines did not show such shifts. ...

. Comment on J1554-2704 . The image here is in good agreement with a 2.3 GHz image from the VLBA Calibrators database. Lovell (in preparation) gives a position of RA=15h 54m 02.47s, Dec=-27 04 40.2", in good agreement with that derived from these observations. The correlating position was 9" offset, but should not affect the quality of the image. VLBApls home page . Last modified: 16 Oct 2000
