A Survey of Herbig Ae/Be Multiplicity

The Astronomical Journal, 2023
Although the majority of Herbig Ae/Be (HAEBE) stars are likely multiple systems, relatively few multiples have been identified. We aim to create a statistically significant survey of HAEBE multiplicity as a function of stellar mass, to shed light on ...

A New Catalog of Am-type Chemically Peculiar Stars Based on LAMOST

The Astrophysical Journal Supplement Series, 2023
A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data Releases 8 (v1.0), 9 (v0), and 10 (v0), which greatly expands the database

Chemical characterization of the globular cluster NGC 5634 associated to the Sagittarius dwarf spheroidal galaxy [PDF]

, 2017
As part of our on-going project on the homogeneous chemical characterization of multiple stellar populations in globular clusters (GCs), we studied NGC 5634, associated to the Sagittarius dwarf spheroidal galaxy, using high-resolution spectroscopy of red

Unresolved Binaries and Multiples in the Intermediate Mass Range in Open Clusters: Pleiades, Alpha Per, Praesepe, and NGC 1039

The Astronomical Journal, 2023
In this study, we continue our project to search for unresolved binary and multiple systems in open clusters exploiting the photometric diagram (H–W2)–W1 versus W2–(BP–K) first introduced in Malofeeva et al. In particular, here we estimate the binary and

Limits on the primordial stellar multiplicity

, 2005
Most stars - especially young stars - are observed to be in multiple systems. Dynamical evolution is unable to pair stars efficiently, which leads to the conclusion that star-forming cores must usually fragment into \geq 2 stars.

Multiple zeta-star values for indices of infinite length [PDF]

arXiv, 2023
In this paper, we consider infinite-length versions of multiple zeta-star values. We give several explicit formulas for the infinite-length versions of multiple zeta-star values. We also discuss the analytic properties of the map from indices to the infinite-length versions of multiple zeta-star values.
