| সারসংক্ষেপ≠ | Zeeman-Doppler imaging is a technique for reconstructing stellar magnetic field maps by combining Doppler broadening of spectral lines with the Zeeman splitting caused by magnetic fields. Pioneered by Jean-Francois Donati in the 1990s, this method reveals how magnetic fields are distributed on stellar surfaces and how they evolve with time. | Asteroseismology is the study of stellar oscillations—tiny brightness and radial velocity variations caused by sound waves resonating inside stars. Proposed by Roger Ulrich in 1970 and established as a major field by the Kepler and TESS space telescopes, asteroseismology provides unprecedented precision in determining stellar masses, ages, and internal structure. | Radiative transfer is the mathematical treatment of how light propagates through matter, including absorption, emission, and scattering. Central to astrophysics and stellar atmosphere modeling, radiative transfer calculations translate physical conditions (density, temperature, composition) into observable spectra and colors, bridging theory and observation. |
