Question
hELLO SIR

sIR I WNAT TO KNOW WHAT IS DIFFERENCE BETWEEN ASTRONOMY  AND ASTROPHYSICS.

Answer
Hello,

There is actually very little difference, given most of modern astronomy is also grounded in modern physics. The primary difference is that astrophysics may go into in in much more detail (e.g. the plasma physics of the Sun and solar flares). Also astronomy may include areas not covered by astrophysics such as:
)
- Astronomical Timekeeping (use of sidereal time, etc. for application to specialist disciplines like astrometry (the precise pinpointing of stellar positions on the celestial sphere

- Celestial Mechanics - including use of specialized mathematics to compute the future positions of planets, asteroids etc.

- Differences between astronomical coordinate systems (e.g. equatorial, horizon, ecliptic etc.) and the mathematics used to convert from one to another.

Expertise

I have more than forty years of experience in Astronomy, specifically solar and space physics. My specialties include the physics of solar flares, sunspots, including their effects on Earth and statistics pertaining to sunspot morphology and flare geo-effectiveness.

Experience

Astronomy: Worked at university observatory in college, doing astrographic measurements. Developed first ever astronomy curriculum for secondary schools in Caribbean. Gave workshops in astrophysics and astronomical measurements at Harry Bayley Observatory, Barbados. M.Phil. degree in Physics/Solar Physics and more than twenty years as researcher with discovery of SID flares. Developed of first ever consistent magnetic arcade model for solar flares incorporating energy dissipation and accumulation. Develop first ever loop solar flare model using double layers and incorporating cavity resonators.
