To probe the star formation ( SF ) process , we present a multi-wavelength study of IRAS 05480+2545 ( hereafter I05480+2545 ) .
Analysis of Herschel data reveals a massive clump ( M _ { clump } \sim 1875 M _ { \odot } ; peak N ( H _ { 2 } ) \sim 4.8 \times 10 ^ { 22 } cm ^ { -2 } ; A _ { V } \sim 51 mag ) containing the 6.7 GHz methanol maser and I05480+2545 , which is also depicted in a temperature range of 18–26 K. Several noticeable parsec-scale filaments are detected in the Herschel 250 \mu m image and seem to be radially directed to the massive clump .
It resembles more of a “ hub-filament ” system .
Deeply embedded young stellar objects ( YSOs ) have been identified using the 1–5 \mu m photometric data , and a significant fraction of YSOs and their clustering are spatially found toward the massive clump , revealing the intense SF activities .
An infrared counterpart ( IRc ) of the maser is investigated in the Spitzer 3.6–4.5 \mu m images .
The IRc does not appear point-like source and is most likely associated with the molecular outflow .
Based on the 1.4 GHz and H \alpha continuum images , the ionized emission is absent toward the IRc , indicating that the massive clump harbors an early phase of massive protostar before the onset of an ultracompact H ii region .
Together , the I05480+2545 is embedded in a very similar “ hub-filament ” system to those seen in Rosette Molecular Cloud .
The outcome of the present work indicates the role of filaments in the formation of the massive star-forming clump and cluster of YSOs , which might help channel material to the central hub configuration and the clump/core .
