Describing protostellar disk structure in Ophiuchus
… mm observations of ten protostellar disks in the Ophiuchus star-forming region in a search for the origins of the substructure. Of the sample of ten, four disks have identified structure, three are smooth disks, and three are ambiguous. The structured disks have wide Gaussian-like rings (σR/Rdisk …

Submillimetre Studies of Pre-stellar and Starless Cores in the Ophiuchus, Taurus and Cepheus Molecular Clouds
… the properties of, starless cores in the Ophiuchus, Taurus and Cepheus molecular clouds. We identify sources in SCUBA-2 850-μm emission, and determine temperatures by fitting a modified blackbody model to their spectral energy distributions, measured using SCUBA-2, PACS and SPIRE data. We …

From Large-scale Molecular Clouds to Filaments and Cores : Unveiling the Role of the Magnetic Fields in Star Formation
… Ammonia survey (GAS) of the L1688 region of the Ophiuchus molecular cloud along with the column density map to determine magnetic field strength profile across dense cores. By applying the CFS method we find that for most cores in Ophiuchus, the mass-to-flux ratio is decreasing radially outward.

High Spatial Resolution Observations of Young Stellar Binaries
… mag) of 158 young stellar objects located in the Ophiuchus molecular clouds is presented. All companions in the separation range 0.13 arcsec to 6.4 arcsec with flux ratios >= 0.1 at the diffraction limit could be detected by using speckle techniques. The degree of multiplicity is 29.1%+-4.3% and …

Die 170-um-Zufallsdurchmusterung mit ISO - Strukturen im kalten Staub der Milchstraße
… der Wolkenkomplexe in Chamaeleon, Taurus und Ophiuchus miteinander verglichen. Eine Staubtemperatur von etwa 13K stellt überall einen Grenzwert dar, der nur in Regionen mit Sternentstehung unterschritten wird. Die höchsten Temperaturen werden in der Rho-Ophiuchi-Wolke gefunden und sind mit …

A spectral and timing study of MAXI J1820+070 during outburst
… X-ray binary, located in the constellation Ophiuchus, garnered attention due to its exceptional outburst in March of 2018. The intense luminosity of MAXI J1820+070, which reached a peak X-ray flux of ∼ 4 Crab, allowed for detailed multi-wavelength campaigns, facilitating comprehensive …

Probing planetary disks: from birth to protoplanets
… an unbiased survey of the evolved disks in the ρ Ophiuchus cloud using ALMA. I measured the flux and radius from ∼ 50 pre-main-sequence stellar systems. I found that binary systems are both dimmer and have smaller disks than their isolated components. I used these results to test if these disks …
