cds-question@unistra.frinterstellar-mediumh-ii-regionsnebulaevisible-astronomyspectroscopyradial-velocityWe report multifiber, medium-resolution spectroscopy of the Rosette Nebula with full spatial coverages, and present a table of the nebular parameters based on the spatially resolved measurements of emission lines. These new observations were conducted through the Medium-Resolution Spectroscopic Survey of Nebulae (MRS-N) on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). Comprehensive analyses were performed on a total of 3854 high-quality nebular spectra; so far, the most extensive spectral data set available for this nebula that encompasses an area of 4.52deg^2^. Various physical parameters, including relative line intensities, radial velocities (RVs), and full width at half-maximums (FWHMs), were derived through measurements of the H{alpha}, [N II] {lambda}{lambda}6548,6584 and [S II] {lambda}{lambda}6716,6731 emission lines detected in the LAMOST MRS-N spectra. For the first time, we found a bow-shaped feature in the spatial distribution of RVs of the Rosette Nebula. Moreover, the spatial distributions of RVs and FWHMs, as well as additional parameters such as gas temperature and turbulent velocity in the vicinity of the nebula, indicate possible interaction between Rosette and the nearby supernova remnant, Monoceros Loop. Our new observations provide indispensable measurements of the Rosette Nebula. The parameter table in particular can be used as valuable constraint on the chemo-dynamical modeling of the nebula, which will enable deeper understanding of the characteristics of this H II region.2025AJ....170..309Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/170/309CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/327 : AKARI Far-Infrared Surveyor YSO catalog (Toth+, 2014)V/156 : LAMOST DR7 catalogs (Luo+, 2019)V/162 : LAMOST DR11 catalogs (Luo+, 2026)VI/64 : Recombination line intensities for hydrogenic ions (Storey+ 1995)J/A+A/567/A108 : Rosette globulettes and shells in the IR (Makela+, 2014)J/MNRAS/458/3479 : SVM selection of WISE YSO Candidates (Marton+, 2016)J/ApJ/856/52 : Kinematic distances of star-forming regions (Wenger+, 2018)J/AJ/162/56 : Radial velocity of 240 YSOs with MMT/Hectochelle (Lim+, 2021)J/A+A/664/A175 : MW low mass young stars from Gaia EDR3 (Prisinzano+, 2022)J/ApJ/942/22 : Brackett em. lines in young star APOGEE sp.
