罗素猜想的经验极限
Empirical Limits on the Russell Conjecture
摘要:
罗素猜想指出,在地球轨道上或在内太阳系或小行星带中存在小型(<1米)中空耐热物体(HoHO)的可能性未经证实。虽然这些物体目前不是任何正在进行的搜索的目标,但我们可以使用目前的光学和红外探测对其存在进行严格限制。HoHO的高反射率部分补偿了它们的小尺寸。因此,我们发现,通过空军空间监视系统,在至少30,000公里的距离内,没有半径大于10厘米的HoHO。在384,000公里(地月距离)的稳定轨道上的这种大小的物体可以通过对同一系统进行更不频繁、更深入的扫描来探测和确认。然而,在近地或火星轨道上仍然可能存在未被探测到的HoHO。我们讨论了在不久的将来用LSST等新望远镜发现这种HoHO的前景。
英文摘要:
The Russell Conjecture states that there is an unproven possibility of small (<1 m) hollow heat-resistant objects (HoHOs) in Earth orbit or otherwise present in the inner solar system or asteroid belt. While such objects are not the current target of any ongoing searches, we can place stringent limits on their presence using current optical and infrared surveys. The high albedo of HoHOs partially compensates for their small size. As such, we find that no HoHOs greater than 10 cm in radius to a distance of at least 30,000 km, by the Air Force Space Surveillance System. Objects of that size in a stable orbit at 384,000 km (the Earth-Moon distance) may be detected and confirmed by more infrequent, deeper sweeps of the same system. However, it remains possible for undetected HoHOs to exist in near-Earth or Martian orbit. We discuss the prospects of finding such HoHOs in the near future with new telescopes such as LSST.
