1. How heavy is Herbig Ae/Be star?Approximately 2 to 8 solar masses
2. What is the evolutionary stage?Pre-main-sequence, actively accreting
3. What is the spectral characteristics?Hydrogen (Ae) and Helium (Be) emission lines
4. What are Herbig Ae/Be stars?Herbig Ae/Be stars are young, bright baby stars that are still growing. They are between 2 and 8 times the mass of our Sun and have not yet started stable hydrogen fusion in their cores.
5. How do Herbig Ae/Be stars differ from T Tauri stars?They are hotter and more luminous than T Tauri stars. They also have stronger infrared light because of the dust in their surrounding disks.

Young Stellar Object (YSO): A star in its earliest stages of evolution, still gathering mass from its parent nebula.
Circumstellar Disk: A disk of gas and dust orbiting a star, from which planets may form.
Spectral Energy Distribution (SED): A plot of a celestial object's brightness across different wavelengths of light.
