具有BDNYC群的褐矮星的动能和亮度

Kinematics and Luminosities of Brown Dwarfs with the BDNYC group

A. R Riedel

摘要:

由于星等的限制,盖亚的调查将不会像其他恒星星族那样深入研究褐矮星的局部种群。虽然盖亚将测量数百或数千颗褐矮星,但我们提出了一种不同的间接方法,其中使用盖亚数据的研究将有助于我们了解褐矮星:识别包含褐矮星的移动群体。盖亚数据的使用将直接有助于解开年龄和质量对褐矮星光谱的影响,这为确定褐矮星演化的经验约束提供了可能性。

英文摘要:

Due to magnitude limits, the Gaia survey will not delve as deeply into the local population of brown dwarfs as it will other stellar populations. While hundreds or thousands of brown dwarfs will be measured by Gaia, we propose a different, indirect method wherein studies using Gaia data will help teach us about brown dwarfs: Identifying moving groups that contain brown dwarfs. This use of Gaia data will directly help attempts to disentangle the effects of age and mass on brown dwarf spectra, which opens the possibilities for determining empirical constraints on brown dwarf evolution.
