Two broad charmed mesons, the D0* and D1′, have recently been observed. We examine the quark model predictions for the D0* and D1′ properties and discuss experimental measurements that can shed light on them. We find that these states are well described as the broad, j=1/2 nonstrange charmed P-wave mesons. Understanding the D0* and D1′ states can provide important insights into the DsJ*(2317), DsJ(2460) states whose unexpected properties have led to renewed interest in hadron spectroscopy.
