New variable star 1.1906 Lyncis

The magnetic Bp star 36 Lyncis II . A spectroscopic analysis of its co - rotating disk

We report on the physical properties of the disk-like structure of B8 IIIp star 36 Lyncis from line syntheses of phase-resolved, high resolution spectra obtained from the International Ultraviolet Explorer archives and from newly obtained ground-based spectra of the Hα absorption profile. This disk is highly inclined to the rotational axis and betrays its existence every half rotation cycle as ...

Luminous Red Variable Star

We report photometry and spectroscopy of the evolution of Nova Sagittarii 1994 #1 (V4332 Sagittarii) during outburst. We compare the photometric and spectral evolution of this outburst to known classes of outbursts – including classical novae and outbursts occurring on symbiotic stars – and find this object does not conform to any known class of outburst. The closest match to the behavior of th...

The MACHO Project LMC Variable Star Inventory : IV . New R Coronae Borealis

We report the discovery of two new R Coronae Borealis (RCB) stars in the Large Magellanic Cloud (LMC) using the MACHO project photometry database. The identiication of both stars has been connrmed spectroscopically. One is a cool RCB star (T eff 5000 K) characterized by very strong Swan bands of C 2 and violet bands of CN, and weak or absent Balmer lines, G-band and 12 C 13 C bands. The second ...

Some Striking New STAR Results

Recent high-statistics Au+Au and Cu+Cu runs at RHIC have provided a wealth of new data that allow STAR to answer several outstanding questions regarding the nature of the hot, dense medium that is created in ultrarelativistic heavy-ion collisions. However, the new data also raise new questions that require further study. Here, we focus on a few qualitatively new results presented by STAR for th...
