ORPHANED PROTOSTARS

Locating of massive protostars

NGC 7538 is known to host a 6.7 and 12.2 GHz methanol maser cospatial with a Ultra Compact (UC) H  region,

Formation of Primordial Protostars

The evolution of collapsing metal free protostellar clouds is investigated for various masses and initial conditions. We perform hydrodynamical calculations for spherically symmetric clouds taking account of radiative transfer of the molecular hydrogen lines and the continuum, as well as of chemistry of the molecular hydrogen. The collapse is found to proceed almost self-similarly like Larson-P...

Search for Binary Protostars

In an effort to shed more light on the formation process of binary stars, we have started a program to study multiplicity among nearby low-and intermediate-mass protostars using the OVRO Millimeter Array. Here, we describe the project and present the first results on the protostellar core in the Bok globule CB 230 (L 1177). At 10 ′′ resolution , the molecular core is resolved into two component...

Quantifying Orphaned Annotations in Hypothes.is

Web annotation has been receiving increased attention recently with the organization of the Open Annotation Collaboration and new tools for open annotation, such as Hypothes.is. In this paper, we investigate the prevalence of orphaned annotations, where a live Web page no longer contains the text that had previously been annotated in the Hypothes.is annotation system (containing 6281 highlighte...
