磁化裸奇异星的热光子

Thermal Photons From Magnetized Bare Strange Stars

Enrique Moreno Méndez, Dany Page, Leonardo Patiño, Patricia Ortega

摘要:

由奇夸克物质(SQM)和电子组成的等离子体具有相当高的等离子体频率(>20 MeV)。因此,一颗致密的恒星由这样的材料组成,一直到它的表面,即,一颗裸露的奇异恒星,将无法辐射出它的热辐射。我们使用MIT-bag模型,并假设SQM是高密度核物质的基态。我们调查是否存在一个磁场将允许传播的辐射频率低于SQM等离子体频率。因此,我们研究了在强磁场(B > 10^{12} G)作用下SQM等离子体中陀螺频率的存在。我们发现,小区域的频谱允许辐射传播由于存在的磁场。很可能从磁化的裸奇异星上可以观察到窄辐射带。

英文摘要:

A plasma made out of strange-quark matter (SQM) and electrons, has a rather high plasma frequency (>20 MeV). Thus, a compact star made of such material all the way up to its surface, i.e., a bare strange star, would be unable to radiate away its thermal emission. We use the MIT-bag model and assume that SQM is the ground state of nuclear matter at high density. We investigate whether the presence of a magnetic field will allow propagation of radiation at frequencies below the SQM plasma frequencies. Hence, we study the presence of gyrofrequencies in a SQM plasma permeated by a strong magnetic field (B > 10^{12} G). We find that small regions in the frequency spectrum allow radiation propagation due to the presence of the magnetic fields. It is likely that narrow bands of radiation would likely be observable from magnetized bare strange stars .
