Brown Dwarfs with Gaia

盖亚项目正在进行一项全天天体测量。作为GAIA数据发布3的一部分，2022年夏季期间，天体测量加速将首次可用。这将使一条识别棕矮星和行星的全新路线成为可能。使用档案数据和新数据的后续行动将涉及对轨道参数的识别、表征和限制。这项研究将是更广泛的后续工作的一部分，识别新的棕矮星并获取后续光谱。盖亚所有棕矮星的光谱可以与盖亚的运动学信息一起用来解释它们的化学成分和年龄。这些数据将与GAIA信息一起使用，特别是低分辨率光谱，预计这将是未来数据发布中可能的数据产品。对盖亚样本的科学利用将使人们能够更安全地了解棕矮星，可能包括当地光度和质量函数的推导，基准的表征，以及物理参数(如年龄/质量)与光度/光谱特征的相关性分析。该项目设想包括让学生成为GAIA联盟的成员，并关注未来GAIA数据发布所产生的数据质量。

The Gaia project is making an all-sky astrometric survey. As part of the Gaia data release 3 during summer 2022 astrometric accelerations will become available for the first time. This will enable an entirely new route to identify brown dwarfs and planets. The follow-up both using archival and new data will be concerned with the identification, characterisation and constraints on orbital parameters. This study will be part of the wider follow-up effort identifying new brown dwarfs and taking follow-up spectra. Spectra for all brown dwarfs in Gaia can be used along with kinematic information from Gaia to interpret their chemical compositions and ages. These will be used alongside the Gaia information in particular also low resolution spectra which is envisaged as a possible data product in future data releases. Scientific exploitation of the Gaia sample will enable a much more secure understanding of brown dwarfs and may include derivation of the local luminosity and mass function, characterisation of benchmarks and correlations analyses of physical parameters such as age/mass with photometric/spectroscopic features. This project is envisaged to include the student becoming a member of the Gaia consortium and also being concerned with the data quality produced for future Gaia data releases.
