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:
No. Stella's first wish was to study medicine and he came for it in New York in 1896 to follow his older brother Antonio who was also a doctor.
Explanation:
Joseph Stella, a famous american futurist painter and artist was born in Italy in 1877 and was sent by his family who were in lawyer's bussiness, to America together with his brother Antonio, to study a medicine.
Stella discovered his art talent by refecting with his paintings and drawings on the 19th century expressionists and left medicine soon, making his progress very quickly towards a recognised artist. His first works included portraits, horses, bridges in expressionist manner.
He become famous with his series ' Black paintings' where he explored simple abstract monochrome forms.
