Astronomers can now learn about the chemical and
orbital properties of asteroids just by identifying their color, guided by the tens of thousands of new asteroids revealed in the survey.
The size and spatial distributions of these families, along with
their orbital properties, composition, and internal structure play a key role in our understanding of the formation and evolution of the solar system.
Unlike the majority of exoplanets discovered through indirect means, the planets that we find through imaging may be followed up with spectroscopy of their gaseous atmospheric content and astrometric monitoring of
their orbital properties — both of which provide important clues to how and where they formed in their natal circumstellar / circumbinary disks.
The scientists fed the ANN with atmospheric observations, known as spectra, from the five worlds and then asked it to classify them using a «probability of life» measurement based on atmospheric and
orbital properties.
We also used radial velocity measurements of the host star, spanning a time range of $ \ sim $ 30 yr, to constrain the companion's mass and
orbital properties, as well as to probe the host star's spectral age indicators and general spectral energy distribution.
The research continues with high - resolution spectroscopy to confirm
the orbital properties of PB3877 and with a photometric follow - up to search for variability.
We first give an overview of different types of interactions, depending on the stellar wind and
orbital properties.
