Only since HD 144432 (SAO 184124, He 3-1141, IRAS 160380-2735) was first identified as a possible Herbig Ae star by Oudmaijer et al. (1992), this southern emission-line object has received considerable attention due to its relative brightness (V 8.17), its late spectral type and the relative isolation from a bona-fide star formation region. The star HD 144432 is a late A-type or perhaps an early F-type star with all the known signatures of being a young object. Because of its relatively late spectral type, along with a very small and rare group of objects, represents a unique bridge toward the less-massive T Tauri stars. We present a collection of archival and original data on HD 144432, ranging from optical photometry, and ultraviolet to near-infrared spectroscopic data. This object, as many massive pre-main sequence objects or Herbig Ae/Be stars, have the potential of harboring embryonic proto-planetary material in its surroundings. We also analyze some possible scenarios of its current status and evolution.
