Investigating “white dwarf 137 pdf hot”
This reads like a terse set of search keywords: “white dwarf”, “137”, “pdf”, and “hot”. Interpreting that, I looked for likely scientific contexts and assembled a short explanatory column covering three plausible meanings and what the literature suggests.
It seems you are requesting a report on a specific astronomical object: "white dwarf 137" (possibly with reference to a "PDF" or "hot"). white dwarf 137 pdf hot

Filter by year (if you want recent models) or by author (e.g., Bergeron, Fontaine, Dufour). Alternative names: GD 137, EGGR 137, WD 1412+520,
Report: Hot White Dwarf GD 137 (Possible Candidate for "White Dwarf 137")
1. Identification
- Alternative names: GD 137, EGGR 137, WD 1412+520, LSPM J1414+5145
- Coordinates (J2000): RA 14h14m, Dec +51°45′
- Type: DA (hydrogen-rich atmosphere) white dwarf
For Students:
- Download and annotate: Use a PDF reader to highlight temperature grids, mass estimates, and flux values.
- Compare models: Look for the comparison between observed spectra (HST/COS) and theoretical models (TLUSTY). The "137" object might be a benchmark for model validation.
- Cite correctly: Note the catalog designation (e.g., WD 0137+349). Use ADS to generate BibTeX.
- Composition: Pure hydrogen (DA type) or helium (DO type) atmospheres due to gravitational settling.
- Cooling sequence: They cool monotonically over billions of years. The "hot" phase lasts only the first ~10-100 million years.
- Visibility: Difficult to observe in optical bands; they shine brightest in UV. Hence, surveys like GALEX (Galaxy Evolution Explorer) and EUVE (Extreme Ultraviolet Explorer) are crucial.
- “Hot white dwarf” describes white dwarfs with high effective temperatures (typically > 25,000 K; some reach 100,000 K or more). These are compact stellar remnants with:
