Athena Tacha is an artist born in Greece in 1936 and was one of the first to design and implement environmental site-specific sculpture in the 70s. She has created many permanent public art works throughout the US and she is very famous for her works in environmental public sculpture. The star fountain is consists of numerous glass columns that are illuminated at night by animated LED/RGBs.
I believe the answer is A
The closer the star the larger The Parallax angle.
The primary mechanism driving the X-ray emission in traditional supergiant high mass X-ray binaries and supergiant fast X-ray transients is the accretion of stellar wind material by a compact object.
We present the first simulation of the fast and dense massive star wind accretion onto a neutron star in this paper, taking into account the effects of the centrifugal and magnetic inhibition of accretion ("gating") caused by the spin and magnetic field of the compact object.
We modeled the nonstationary radiatively generated wind of an O-B supergiant star using a radiative hydrodynamical code, and then we positioned a neutron star with a fixed magnetic field and spin period at a specific distance from the massive companion.

Answer:
- Clef is a symbol at the left end of the staff showing the pitch of the notes written on the staff.
- The treble clef is a type of clef that is placed above middle C on the second-lowest line of the staff.
- The musical alphabet is the notes of music that are sung or played. They go from A, B, C, D, E, F, G and then repeat.
