| Observations at radio to (sub)millimeter wavelengths are particularly important for star formation studies. Unlike optical lights, radiation within the above range can better penetrate gaseous and dusty regions where stars are formed and provide critical information of the innermost part of the clouds.
The two figures shows results from observations at 7 mm with the Very Large Array (VLA) toward an active low mass star formation region L1551 IRS5, where a binary system is forming. The lower resolution image demonstrates the distribution of the surrounding circumbinary dust while the high resolution image probes both the circumstellar dust disks and ionized jets associated with the protostars in this region. The detection of a new dust component south-east of the north YSO shown in the high resolution image further suggests this known binary system may actually be a triple system!
