摘要
我们介绍了由MOST 1卫星获得的roAp恒星HD 134214的10.27小时光度测量。这颗恒星是单周期的，振荡频率为2948.97±0.55 μHz。这与早期的地面光度测量活动(如Kreidl et al. 1994)是一致的。我们没有检测到Kurtz等人(2006)在最近的光谱研究中发现的任何额外频率，其幅度限制为0.36毫安(2σ显著性限制)。
We present 10.27 hrs of photometry of the roAp star HD 134214 obtained by the MOST 1 satellite. The star is shown to be monoperiodic and oscillating at a frequency of 2948.97 ± 0.55 μHz. This is consistent with earlier ground based photometric campaigns (e.g. Kreidl et al. 1994). We do not detect any of the additional frequencies identified in the recent spectroscopic study by Kurtz et al. (2006) down to an amplitude limit of 0.36 mmag (2σ significance limit).
