Materials known to exist at Pluto's surface from ground - based spectroscopic observations include highly volatile cryogenic ices of N2 and CO, along with somewhat less volatile CH4 ice, as well as H2O and C2H6 ices and more complex tholins that are inert at Pluto surface temperatures.

The results of follow - up observations (see Table 2) are a mixture of results from photometric follow - up (Deeg et al. 2009), which identifies contaminating» diluted EB's that are more than about 2 distant from the third star - which usually coincides with the observing target -, and from spectroscopic (radial velocity) results, which can only identify signals from sources that fall into the spectrograph's entry slit; that is, they have to be very close (less than 1 - 2) to the target.

Recently, Hallinan et al. (2015) reported simultaneous radio and optical spectroscopic observations (obtained with the Karl G. Jansky Very Large Array (VLA) radio telescope and the Double Spectrograph (DBSP) on the 5.1 - m Hale telescope, respectively) of auroral emissions of an object at the end of the stellar main sequence (i.e. at the boundary between stars and brown dwarfs).

The latter would enable the most detailed possible analysis, providing a crucial link with remote spectroscopic observations and the compositions of meteorites in order to develop a much wider understanding of these small bodies, their properties, and what they can tell us about the evolution of the solar system.

Spectroscopic observations taken with the GTC - 10.4 m telescope reveal a broad (FWHM ~ 1100 km / s), double - peaked H alpha emission line from which we constrain the radial velocity semi-amplitude of the donor to be K2 > 250 km / s.

With photometric and spectroscopic observations, we have been able to learn about the surface properties and the physical processes acting on these large planetoids.

In order to identify false positives and confirm transiting exoplanets, we have assembled a follow - up network (KELT - FUN) to conduct imaging with higher spatial resolution, cadence, and photometric precision than the KELT telescopes, as well as spectroscopic observations of the candidate host stars.

To further investigate, astronomers led by Nanda Rea of the University of Amsterdam sought help from NASA's Chandra and Nuclear Spectroscopic Telescope Array, or NuSTAR, to follow up with the observations.

The baffling and strange behaviours of black holes have become somewhat less mysterious recently, with new observations from NASA's Explorer missions Swift and the Nuclear Spectroscopic Telescope Array, or NuSTAR.
