stars, we tried machine-learning algorithms to search for class-one and class-two chemical peculiars (CP1 ...
and 2708 CP2, in which 6917 CP1 and 1652 CP2 are newly discovered.
We also list the spectral features to separate CP1 from CP2 discovered through XGBoost.
The log g of CP1 ranges from 2.8 to 4.8 dex, peaking at 4.5 dex, and of CP2 it ranges from 2.0 to 5.0 ...
The [Fe/H] of CP1 and CP2 are from -1.4 to 0.4 dex, and the [Fe/H] of CP1 are on average higher than ...
