几个小时前,收到英国杂志MNRAS 的来信,我们的一篇论文被该杂志接收,将在一个月内正式发表。这算是在春节当天收到的一个大红包吧。
这次论文能够被接收,多亏了一位美国教授的鼎力合作。他为我们的论文增加了很好的扩展,使得它成为一篇像模像样的论文。因此,论文的作者一共有三个人。
为了修改这篇文章,我们之间进行过反复的磋商,有过数十封的往来信件。在这期间真正领略了正牌专家的严谨态度,也学到了很多知识。
标题是:“Testing the rotating lighthouse model with the double pulsar system PSR J0737-3039A/B”
摘要:
Each of the two pulsars in the double pulsar PSR J0737-3039A/B system exhibits
not only the pulses emanating from itself, but also displays modulations near the pulse
period of the other (McLaughlin et al. 2004a,b). Freire et al. (2009a) have put forward a
technique using the modulation of B by A to determine the sense of rotation of pulsar
A relative to its orbital motion, among other quantities. In this paper, we present
another technique with the same purpose. While the Freire et al. (2009a) approach
analyzes pulse arrival times, ours instead uses periods or frequencies (their inverses),
which can be experimentally determined via power spectral analysis similar to that
used in pulsar searches. Our technique is based on the apparent change in spin period
of a body when it is measured from an orbiting platform (the other pulsar), and is
shown to be entirely analogous to the difference between the sidereal and solar spin
period of the Earth (i.e., the sidereal and solar day). Two benefits of this approach
are its conceptual and computational simplicity. The direct detection of spin with
this technique will observationally validate the rotating lighthouse model of pulsar
emission, while the detection of the relative directions of spin and orbital angular
momenta has important evolutionary implications. Our technique can be used on
other binary systems exhibiting mutually induced phenomena.
