The study found coexistence of native
metallicity and ferroelectricity in bulk crystalline tungsten ditelluride (WTe2) at room temperature.
By figuring out the abundance of different elements within the star, or its
metallicity, researchers can now further refine the age of the object, Moss and Kloc reported in two separate AAS poster presentations.
Residing in the same part of the Milky Way galaxy as our own solar system, the star is believed to be up to 13.5 billion years old which is evidenced by its extremely low metal content, or
metallicity, Xinhua news agency reported.
M54 has been proposed as the actual nucleus of the galaxy, but a 2008 investigation using velocity and
metallicity data concluded M54 formed independently and plunged to its current location at 87,000 light-years distant due to dynamical friction.
Another relevant uncertainty concerning the progenitor systems for LGRBs is the role of
metallicity Z.
Watauchi et al., "Charge ordering, commensurability, and
metallicity in the phase diagram of the layered," Physical Review Letters, vol.
To maintain consistency with existing Solar data, in this work we consider the high
metallicity Standard Solar Model (SSM) [21].
We present a review of the literature and new photometry of the cluster looking specifically at potentially new members of the system and present plans for a spectroscopic campaign to determine
metallicity of the cluster.
