CK Vul: reborn perhaps, but not hibernating

Repetitive perhaps, but certainly not boring

Parental Advice: Given Perhaps, but Not Received.

We all think we give good advice, and we think we do it well. We’ve mastered the anticipatory guidance section of the well-child or nursery visit. We have our formula: we cover the salient topics, throw in some personal experience, and assume our parental advice on child rearing has been received and understood. Unfortunately, as shown by Eisenberg et al in this issue of Pediatrics, we appear t...

CK Vul as a Candidate Eruptive Stellar Merging Event

CK Vul (Nova Vul 1670) is one of the most mysterious objects among erupting stellar objects. Past studies have suggested that CK Vul is a final helium-flash object resembling V605 Aql and V4334 Sgr (Sakurai’s object). The peculiar outburst light curve of CK Vul, however, had no similar counterpart among the known eruptive objects. Furthermore, the presence of hydrogen in the proposed remnant se...

Perhaps Unidimensional Is Not Unidimensional

Miller (1956) identified his famous limit of 7 ± 2 items based in part on absolute identification-the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types. Recent research, however, has identified several exceptions. We...
